Getting a SIM card

AIS, TrueMove, and DTAC all offer tourist and long-term SIM options with generous data packages, purchasable at malls, convenience stores, or provider shops with just a passport — no proof of address needed, unlike a bank account, which makes getting a SIM the natural first practical task on arrival, well before anything else on this list. Long-term monthly plans with substantial data run roughly 300–600 THB/month.

Which provider

All three have solid coverage in Hua Hin town; AIS is generally considered to have the strongest overall network reliability in the wider Prachuap Khiri Khan region, worth confirming against your specific area if you’re settling somewhere more rural like Pranburi or further inland areas where coverage can vary more between providers than it does in the town centre.

eSIM, prepaid or postpaid?

An eSIM is a digital SIM profile built into a compatible phone. It does the same job as a physical SIM for calls, messages and mobile data, but you download or activate it electronically instead of inserting a plastic card. Thai SIM-registration rules still apply, and your phone must support eSIM.

AIS, True and dtac all offer eSIM options. AIS supports eSIM with both prepaid and postpaid services; dtac says its eSIM is available to prepaid and postpaid customers; and True sells tourist eSIM products. Availability and activation steps depend on the plan and device, so check the provider’s current terms before buying.

Prepaid is usually the simplest choice for a short stay: pay in advance, top up when needed and avoid a monthly contract. Postpaid can suit long-term residents who want a regular bill, larger plan choices or bundled services. Foreign customers may need passport identification and additional checks for some postpaid plans.

Remote workers: keep a mobile data package as backup to your home fibre. Power and internet cuts happen during storms, and a hotspot keeps you online.

Home internet

Fibre internet is widely available and inexpensive: 500–800 THB/month for speeds (typically 300Mbps–1Gbps) well beyond what most households actually need, even for demanding video calls or multiple simultaneous users. True, AIS, and 3BB are the main fibre providers. Installation is usually straightforward and quick once a building is already wired for fibre — often within a few days of requesting service — worth checking with a landlord or condo juristic office whether fibre is already run to the unit before signing a lease, since a building that isn’t already wired can mean a longer wait or, rarely, no fibre option at all if it’s genuinely remote.

Working remotely

Fibre speeds comfortably support video calls and remote work for most professional use cases, including simultaneous video conferencing and file transfers. A mobile data SIM as backup during any outage is cheap enough to be worth having regardless — Thailand’s fibre network is generally reliable, but occasional outages happen, and having a mobile hotspot backup means a brief outage doesn’t derail an important call.

Setting up a router and home network

Most fibre providers include a router as part of the installation, though some expats prefer to add their own mesh network system for larger villas or homes with weak signal in far rooms — worth checking what’s included versus what you’ll need to source separately when comparing provider quotes.

Where this connects

Frequently asked questions

Where can I buy a SIM card?

At the airport on arrival, at network shops in the malls, or at 7-Eleven. Registering with your passport is mandatory.

Is the internet fast enough for video calls?

Yes, fibre connections in Hua Hin easily handle video calls and streaming. Check availability for your exact address before signing a lease.

Can I keep my home phone number?

Many expats keep their home SIM on a cheap plan or eSIM for banking verification codes, and use a Thai SIM for daily life.
