True Corporation emerged as Thailand's dominant carrier after merging with DTAC in 2023, now controlling approximately 52% of the mobile market. This market position allows them to offer extensive coverage throughout Thailand, though their tourist packages come with several important limitations that visitors should understand.
The carrier offers various tourist SIM options through both True and DTAC brands, which can confuse visitors since both are now the same company. Their most popular packages are marketed as "unlimited" plans, though this term proves misleading once you understand the fair usage policies that severely restrict actual data usage.
| Plan Category | Duration | Cost (THB/USD) | High-Speed Data | Key Features |
|---|---|---|---|---|
| 8-Day Infinite | 8 days | 449 baht ($13.85) | 2.5GB daily FUP | Unlimited after throttling to 384kbps |
| 15-Day Infinite | 15 days | 599-899 baht ($17-26) | 3GB daily FUP | Free WiFi, social apps |
| 30-Day Infinite |
True Corporation's advantages stem primarily from their market dominance and infrastructure investment. With 93% nationwide 5G coverage and 99% coverage in Bangkok, they offer reliable connectivity in most urban areas. Their extensive network of stores at airports and shopping malls makes purchasing relatively convenient, though prices vary significantly by location. The inclusion of enhanced social media packages with TikTok, Instagram, and Pinterest provides added value for social media users.
However, the limitations often outweigh these advantages for international visitors. The deceptive marketing of "unlimited" plans frustrates many users who discover speeds throttle to an unusable 384kbps after consuming just 2.5-3GB daily. Airport locations charge 30-50% premiums over city stores for identical packages, meaning families can waste significant money on convenience. Language barriers persist throughout the purchase and support process, with limited English-speaking staff and Thai-language apps creating ongoing challenges.
Beyond tourist packages, True offers standard prepaid options that often provide better value for savvy travelers who can navigate the Thai-language registration process. These plans avoid some of the restrictive fair usage policies of tourist packages but require more effort to access and manage.
| Plan Type | Cost (THB/USD) | Data Allowance | Validity |
|---|---|---|---|
| Daily | 29 baht ($0.85) | 1.5GB | 24 hours |
| Weekly | 99 baht ($2.90) | 7GB | 7 days |
| Monthly | 199-599 baht ($5.80-17.50) | 10GB-50GB | 30 days |
These regular prepaid plans come with their own set of challenges. The registration process typically requires Thai language skills or finding staff willing to help tourists access non-tourist plans. Top-up procedures involve Thai-language USSD codes or apps that assume local knowledge. Additionally, SIM validity expires after 30-90 days regardless of remaining credit, making them unsuitable for visitors planning return trips.
Setting up True Corporation service involves multiple steps that vary significantly depending on where you purchase and which package you select. Understanding the process beforehand helps avoid common frustrations and ensures you get the best value for your needs.
| Step | Action | Details | Requirements |
|---|---|---|---|
| 1 | Choose Purchase Location | Airport (expensive) or city store (cheaper) | Research prices first |
| 2 | Bring Passport | Mandatory registration since 2017 | Physical passport required |
| 3 | Select Package | Staff often pushes expensive options | Know what you need |
The setup process typically takes 30-45 minutes at airport locations, though this can extend during peak arrival times when queues form. City stores may offer faster service but require navigating Bangkok traffic and finding locations in unfamiliar shopping malls. The mandatory passport registration adds complexity, as staff must photograph your documents and enter details into their system before activation can proceed.
Different purchase locations offer varying experiences and prices that significantly impact your total cost and convenience. Airport counters provide English-speaking staff and extended hours but charge substantial premiums for this convenience. City stores offer standard pricing but may have limited English support and restricted hours. Convenience stores like 7-Eleven sell SIM cards but rarely can activate tourist packages properly.
| Location | Price Premium | Wait Time | English Support | Operating Hours |
|---|---|---|---|---|
| Suvarnabhumi Airport | +30-50% | 15-45 minutes | Good | 24/7 |
| Don Mueang Airport | +25-40% | 10-30 minutes | Fair | 6am-midnight |
| Bangkok Mall Stores | Standard |
Understanding how True Corporation's setup complexity compares to alternatives helps you make an informed decision about whether the traditional carrier approach suits your needs or if modern eSIM solutions offer better value.
| Step | True Tourist SIM | True Roaming | Standard eSIM Process | Truely Process |
|---|---|---|---|---|
| 1 | Visit physical store | Contact customer service | Visit provider website | Visit Truely website |
| 2 | Passport registration | Request roaming activation | Select Thailand | Select any destination |
Device compatibility determines whether you can use True Corporation services effectively. Most modern unlocked smartphones work with Thai networks, though some regional variations may experience reduced functionality or network speeds.
| Device Type | Compatible Models | Verification Method | Special Notes |
|---|---|---|---|
| iPhone | iPhone 6 and newer | Settings > General > About | Check for carrier lock |
| Samsung | Galaxy S6 and newer | Settings > Connections > SIM manager | Best compatibility |
| Google Pixel | Pixel 2 and newer | Settings > Network & Internet | Good True compatibility |
True Corporation operates on standard Thai frequencies that align with most international devices. Their 5G network uses bands n1, n3, n28, and n78, providing 93% coverage nationwide. The 4G LTE network operates on bands 1, 3, and 8, ensuring broad device compatibility. Older devices fall back to 3G on 850/2100 MHz frequencies, maintaining basic connectivity even with older phones.
True Corporation's reliance on traditional SIM technology creates multiple friction points for international visitors. The requirement to visit physical stores, navigate language barriers, and complete passport registration adds significant time and complexity to what should be a simple connectivity purchase. This traditional approach contrasts sharply with modern eSIM solutions that can be purchased and activated online in minutes.
Standard eSIM providers have improved upon traditional carriers by eliminating store visits, though they still require manual QR code installation for each country visited. These first-generation eSIM solutions typically cover 50-100 countries but need new profiles for each destination, creating management overhead for multi-country travelers.
Truely's second-generation Switchless™ technology represents a fundamental advancement beyond both traditional SIMs and first-generation eSIMs. With one-click installation that works across 190+ countries, automatic network switching between destinations, and no manual configuration requirements, Truely eliminates the friction that plagues both traditional and standard eSIM solutions.
True Corporation's marketing of "unlimited" data plans creates significant frustration when visitors discover the restrictive fair usage policies hidden in the fine print. After consuming just 2.5-3GB daily, speeds throttle to 384kbps, rendering the connection nearly useless for modern applications like maps, video calls, or social media uploads.
This throttling typically hits by early afternoon for active users, forcing them to purchase additional data packages at 100-300 baht ($3-9) for just 1-3GB lasting only 24 hours. These add-ons can double or triple the actual daily cost of connectivity, turning what seemed like an affordable option into an expensive trap.
Most international eSIM providers offer more transparent pricing with clearly stated data limits and no hidden throttling. Daily rates typically range from $4.50-15 with specific data allowances that help users understand exactly what they're purchasing. Truely goes further by providing genuine unlimited data with a generous 10GB daily fair use policy before reducing to a still-usable 512kbps, four times the high-speed allowance of True's restrictive plans.
True Corporation's pricing strategy exploits the convenience needs of arriving tourists through significant airport premiums. The same 8-day SIM package that costs 399 baht ($11.50) in Bangkok shopping malls sells for 599 baht ($17) at Suvarnabhumi Airport, a 50% markup for identical service.
This pricing discrimination particularly affects families, who might waste 800 baht ($23) purchasing four SIMs at airport prices instead of city rates. The lack of transparent pricing at airport counters means many visitors don't realize they're overpaying until they see the same packages elsewhere. Combined with long queues during peak arrival times and staff who push the most expensive options, the airport experience often leaves visitors feeling exploited rather than welcomed.
Understanding actual costs across different travel scenarios reveals why alternatives often provide better value than True Corporation's seemingly affordable packages:
| Travel Scenario | True Corporation Cost | Standard eSIM Cost | Truely Cost | Truely Advantage |
|---|---|---|---|---|
| 3-Day Bangkok Trip | 449 baht ($13.85) minimum | $13.50-45 (3 days) | $7.50-16.56 | Pay only for days used |
| 1-Week Island Hopping | 449-599 baht ($13.85-17) + add-ons | $31.50-105 (7 days) | $17.50-38.64 | No throttling frustration |
The evolution from traditional SIM cards to modern eSIM technology has transformed international connectivity, but not all eSIM providers offer the same level of innovation. While most still use first-generation technology requiring new installations for each destination, Truely has developed revolutionary Switchless™ technology that fundamentally changes the user experience. Learn what an eSIM is to understand how this technology enables seamless global connectivity through a single installation that works across 190+ countries.
True Corporation's restrictive 2.5-3GB daily limits force users to constantly monitor usage and purchase expensive add-ons. Other eSIM providers typically offer fixed data packages that may run out mid-trip. Truely takes a different approach with genuine unlimited data that includes 10GB of high-speed usage daily before reducing to a still-functional 512kbps. This generous policy means you can use maps, social media, and communication apps throughout the day without worrying about sudden throttling or overage charges.
Language barriers and limited support hours plague traditional carriers like True Corporation, where English assistance depends on finding the right staff member. Standard eSIM providers typically offer email support during business hours, which doesn't help when you need immediate assistance at 2am in Bangkok. Truely provides 24/7 live chat support in multiple languages, ensuring you always have access to help regardless of time zone or location.
True Corporation locks you into their single network, which means suffering through congestion at popular tourist spots with no alternatives. Truely's 700+ network partnerships worldwide provide automatic access to multiple carriers, ensuring you always connect to the strongest available signal. When True's network overloads during Songkran or at Full Moon parties, Truely seamlessly switches to AIS or other available networks, maintaining your connectivity when you need it most.
Traditional carriers force you into rigid plans that waste money on unused days. Truely's unique start and stop functionality lets you pause service between trips, reactivating instantly when you need connectivity again. This flexibility proves invaluable for frequent travelers who want consistent service without paying for days they're not traveling.
Problems with True Corporation services often stem from language barriers, technical limitations, or misunderstood policies. Understanding common issues and their solutions helps resolve problems quickly:
| Problem | Cause | Solution | Additional Steps |
|---|---|---|---|
| "No Service" | Incomplete passport registration | Return to store with passport | Bring physical passport |
| "Data Not Working" | Wrong APN settings | Manual configuration required | Settings > Network > APN |
| "Already Throttled" | Hit 2.5GB daily limit | Buy add-on package | 100-300 baht ($3-9) for 1-3GB |
Successfully using True Corporation services requires understanding the system's quirks and planning accordingly. These practices help minimize frustration and maximize value:
| Category | Best Practice | Why It Matters | Implementation |
|---|---|---|---|
| Pre-Purchase | Research city store locations | Avoid airport premiums | Save 30-50% on cost |
| Documentation | Bring physical passport | Required by law | Copies sometimes rejected |
| Package Selection | Know exact needs beforehand | Staff pushes expensive options | Resist upselling |
Since True Corporation offers limited international roaming primarily for Thai residents, visitors planning multi-country trips need alternative strategies:
| Travel Phase | Best Practice | Benefit | Implementation |
|---|---|---|---|
| Pre-Travel | Consider alternatives | True has limited roaming | Compare eSIM options |
| In Thailand | Stay in covered areas | 93% 5G coverage claimed | Cities better than islands |
| Data Usage | Front-load morning activities | Throttling hits afternoon | Download maps early |
True Corporation's single network dependency creates unavoidable dead zones and congestion issues at popular tourist destinations. When their network struggles, users have no alternatives except finding WiFi or suffering through poor connectivity. Standard eSIM providers face similar limitations since they typically partner with just one carrier per country.
Truely's multi-network approach fundamentally solves this problem through automatic switching between 700+ partner networks. When True's network overloads at Maya Bay or during Full Moon parties, Truely seamlessly connects to AIS or other available carriers, maintaining service quality when others fail.
The restrictive 2.5-3GB daily limits imposed by True Corporation create a predictable pattern of frustration for visitors. Morning usage for navigation and photo uploads exhausts the allowance, leaving afternoons and evenings with barely functional 384kbps speeds. Standard eSIM providers vary in their approaches, with some offering genuine unlimited data while others impose their own caps.
Truely's generous 10GB daily high-speed allowance quadruples True's limit, accommodating even heavy users throughout the day. After reaching this threshold, the 512kbps reduced speed still supports messaging, maps, and music streaming, unlike True's unusable 384kbps throttling.
Language barriers permeate True Corporation's support system, from Thai-language apps to limited English phone support. Finding help requires either visiting stores during business hours or struggling with automated systems designed for Thai speakers. Standard eSIM providers typically offer email support with response times measured in hours or days.
Truely's 24/7 live chat support in multiple languages ensures immediate assistance whenever needed. Their specialized eSIM expertise means agents understand common travel connectivity issues and can resolve problems quickly without language barriers or time zone limitations.
True Corporation's pricing strategy exploits information asymmetry, charging different prices at different locations while hiding fair usage limitations in fine print. The real cost often doubles once necessary add-on packages are included. Standard eSIM providers offer fixed online pricing but may have their own hidden limitations.
Truely maintains complete pricing transparency with the same $2.50-5.52 daily rate regardless of when or where you purchase. No hidden throttling, no location-based premiums, and no surprise add-on requirements mean the price you see is exactly what you pay.
Understanding which service works best for different travel patterns helps you make the right decision:
| Use Case | True Corporation Suitability | Standard eSIM Suitability | Truely Suitability | Best Choice |
|---|---|---|---|---|
| Short Bangkok Visit (1-3 days) | Poor (8-day minimum waste) | Good (daily rates) | Excellent (exact days) | Truely |
| Island Hopping Week | Poor (coverage gaps + throttling) | Depends on provider | Excellent (multi-network) | Truely |
True Corporation offers tourist SIMs starting at 449 baht ($13.85) for 8 days but misleadingly advertises "unlimited" data that throttles to unusable 384kbps after just 2.5-3GB daily. Airport prices are 30-50% higher than city stores.
Visit True or DTAC stores at airports (expensive) or shopping malls (standard pricing). You'll need your physical passport for mandatory registration. The process takes 30-45 minutes typically.
True's Fair Usage Policy throttles speeds to 384kbps after consuming 2.5-3GB daily. This makes afternoon internet nearly unusable for maps, social media, or video calls. Additional high-speed data costs 100-300 baht ($3-9) per 1-3GB.
True claims 93% nationwide 5G coverage but island coverage varies significantly. Popular destinations like Phi Phi and Full Moon Party venues experience severe network congestion during peak seasons.
True Corporation offers limited international roaming primarily for Thai residents. International visitors should consider alternatives like Truely eSIM for multi-country travel at $2.50-5.52/day.
Airport locations charge 30-50% premiums for convenience. The same 8-day package costs 599 baht ($17) at Suvarnabhumi Airport but only 399 baht ($11.50) at Bangkok mall stores.
AIS offers slightly better coverage (95% vs 93% 5G) and faster speeds but similar fair usage restrictions. For genuine unlimited data, Truely eSIM at $2.50-5.52/day surpasses both with 10GB daily high-speed and access to multiple networks.
True Corporation's services provide widespread coverage in Thailand but fall significantly short for international visitors due to deceptive marketing, restrictive policies, and tourist exploitation. The misleading "unlimited" claims and airport premium pricing make True particularly frustrating for travelers seeking transparent, reliable connectivity.
True Corporation's key advantages include:
True Corporation's significant limitations create visitor frustration:
How eSIM providers compare shows significant differences. Standard eSIM providers offer daily rates of $4.50-15 per day but require multiple eSIMs per destination. Truely offers superior value with lowest rates of $2.50-5.52 per day and revolutionary single-eSIM solution. Most providers use first generation technology requiring QR codes per country. Only Truely provides second generation Switchless™ with automatic global switching.
