What do you need to get connected?
AIS, True and dtac: which provider is best?
All three major networks can work well. The right choice depends on where you live, how much data you use and whether coverage or price matters most.
Strong all-round coverage
Often chosen by travellers, professionals and people who prioritise reliable coverage across Thailand.
- Wide national network
- Strong 4G and 5G availability
- Large shop and service network
Bundles and broad availability
A popular option for mobile, home internet and bundled services, particularly in larger towns and cities.
- Competitive package range
- Mobile and fibre bundles
- Convenient retail presence
Simple, value-led plans
Often attractive for straightforward prepaid packages and users focused on price and ease of use.
- Easy prepaid choices
- Useful app-based management
- Good urban coverage
Tourist SIM, local prepaid or postpaid?
Tourist SIMs are convenient on arrival and usually include a ready-made data package. Local prepaid SIMs can be cheaper and more flexible for longer stays. Postpaid plans may suit residents who want regular billing, larger data allowances or handset bundles.
What you may need
- Your passport
- A Thai address or accommodation details
- A compatible unlocked phone
- A payment method
- For some postpaid plans, extra residency or visa evidence
eSIM, physical SIM and phone compatibility
eSIM
Useful for instant activation, dual-number setups and keeping your home-country SIM active for banking codes.
Physical SIM
Simple, widely available and often easier to replace or move between compatible devices.
Check your phone
Confirm that it is unlocked and supports the frequencies, 4G/5G bands, VoLTE and eSIM features you intend to use.
Keep access to OTPs
Plan how you will receive banking and account verification codes before changing numbers or cancelling your old plan.
Fibre, 5G home internet or a mobile hotspot?
For stable video calls, streaming and everyday work, fibre is usually the strongest long-term solution where available. A 5G router or mobile hotspot can be better for short stays, quick setup or locations without fibre.
Build a reliable connection for work
Check the actual address
Ask which providers already serve the building or house.
Test mobile coverage
Check signal in the room where you will work.
Plan a backup
Keep a second network or hotspot ready for outages.
Check upload speed
Video meetings and cloud backups need more than a headline download speed.
