Mobile phones, internet and streaming in Southeast Asia
Your phone number is a utility, an identity check and a key to important accounts. Keep your home-country number working while you set up a correctly registered local line, prove the home broadband at the exact address, and move streaming and app-store accounts without losing family access.

The connectivity rule
Keep both numbers until every important account works
Use a local number for everyday life, but keep your home-country number able to receive critical messages while you change and test account-recovery methods one service at a time. Porting, cancelling and changing devices together can lock you out unnecessarily.
Compare the five destinations
Phone plans, home internet and entertainment work differently in each country
Use the regional comparison for the shared setup, then open the destination guide for current provider examples, city differences, streaming-account steps and address checks.
Why two numbers help
Keep home-country access while setting up daily life abroad
Home-country continuity number
- Banks, government services and existing account recovery
- Provider permits the plan and overseas use
- Payment, roaming and replacement options tested
- Authenticator and recovery codes added where available
Destination number
- Registered truthfully with local documents
- School, landlord, delivery, banking and services
- Known validity, top-up and number-retention rules
- Recovery is accessible to the right adult
SIM registration · checked 2 September 2026
Registration can affect validity and network access
| Destination | Foreign-customer setup | Distinctive issue | Practical action |
|---|---|---|---|
| 🇹🇭 Thailand | Register with the operator using passport/approved identity and current verification process. | NBTC has tightened controls on numbers registered to foreign users. | Use an official operator shop; keep registration and avoid pre-registered reseller SIMs. |
| 🇲🇾 Malaysia | Prepaid registration uses verified identity; MCMC guidance distinguishes passport-only tourists from work/student evidence. | Passport-only tourist validity has been limited under the registration framework. | Ask how the line converts or remains valid once resident documents arrive. |
| 🇻🇳 Vietnam | Subscriber information must accurately match accepted identity records. | Authorities and carriers disconnect SIMs with incorrect/unmatched subscriber information. | Register directly with the carrier and check the line is under your own identity. |
| 🇮🇩 Bali / Indonesia | Foreigners register with passport/KITAS/KITAP under operator process; new-number biometric verification became fully effective 1 July 2026. | A foreign-bought device also needs Customs IMEI registration to use an Indonesian SIM. | Complete official SIM and IMEI steps; foreign-SIM roaming is a separate exception. |
| 🇵🇭 Philippines | Tourists: passport, Philippine address proof and return/onward ticket. Other visa holders: applicable status/work/study evidence. | Tourist-registered SIM is valid for 30 days under RA 11934; a minor registers under parent/guardian. | Choose the correct registration category and plan a lawful continuity route beyond the tourist period. |
An extra check for Indonesia
A registered SIM cannot fix a blocked device IMEI
Use the official Customs route. Indonesian Customs says phones, cellular handheld computers and tablets acquired abroad require IMEI registration to use an Indonesian cellular network. Taxes depend on customs value and allowance; roaming on a foreign SIM is treated differently.
Broadband is a property fact
Test the exact unit, not the building brochure
Technology, provider, advertised and measured speeds, upload, latency and data/fair-use terms.
Router location, concrete walls, floor area, mesh need, wired ports and power stability.
Installation date, landlord consent, minimum term, deposit, relocation and cancellation.
Different mobile network if possible, hotspot plan, power bank/UPS and alternate work site.
- Run several tests from the actual work and study locations at peak call times.
- Check upload, latency and packet stability—not download speed alone.
- Make a video call with cameras on while another device streams or uploads.
- Test mobile signal indoors with doors/windows in their normal position.
- Ask what happens during local power cuts and who controls building network equipment.
Streaming and entertainment subscriptions
Do not move every digital account on the same day
Netflix, Spotify, Apple and Google use different country, billing, family and catalogue rules. Broadband bundles can add another account layer, so keep a record of who owns each subscription and what happens when the promotion or home contract ends.
Netflix and video services
A permanent country move can change plan price, currency, payment methods and catalogue. Netflix tells movers to cancel and sign up again in the destination; other services have their own process.
Music and recurring billing
Spotify says Premium country changes may require a payment method issued in the new location. Check renewal dates before cancelling a home-country card.
Apple family accounts
Spend account balance and review subscriptions, pre-orders and Family Sharing before changing region. Some content or services may not be available in the new store.
Google Play families
A location and local payment method are required; family-group membership, balances and a waiting period between country changes can affect the move.
Make a family subscription list before departure. Record account owner, renewal date, payment method, child profiles, downloaded content, app-store country, device support and whether a broadband/mobile bundle is involved.
Move two-factor authentication safely
Change one important account at a time
- List every accountBanks, government, email, password manager, work, school, health, insurance and investments.
- Add recovery optionsAuthenticator, passkey, backup code, second trusted adult or verified email where supported.
- Test from abroadSign out and complete a controlled recovery while both numbers and the old device still work.
- Change selectivelyUse the local number only where it will remain valid and accepted.
- Retire the old number carefullyCancel or port the home-country line only when no critical service silently depends on it.
Common questions
Questions about phones, internet and streaming in Southeast Asia
Should I keep my home-country mobile number after moving abroad?
Usually keep it until every bank, government service, insurer and account recovery route has been tested overseas. Check the provider permits long-term roaming or overseas residence, maintain payment and add non-SMS recovery options where possible.
Can foreigners buy a local SIM in Southeast Asia?
Yes in common circumstances, but registration is mandatory and documents vary. Use an operator's official shop or authorised channel, register in your own name and keep the confirmation. Tourist and resident validity can differ.
Will my overseas phone work with an Indonesian SIM?
A phone obtained outside Indonesia may need its IMEI registered with Customs to use an Indonesian cellular network. Inbound roaming with a foreign SIM does not require IMEI registration. Declare and register through the official route on arrival; duties or taxes can apply.
Do tourists need to register SIMs in the Philippines?
Yes. The SIM Registration Act requires foreign tourists to provide passport, Philippine address evidence and a return/onward ticket. The tourist SIM is temporarily valid for 30 days under the Act; other visa holders provide applicable immigration, work or study evidence.
Is an airport SIM the best option?
It can be a useful arrival bridge, but compare validity, renewal, resident conversion, number retention, eSIM support and coverage at the home and school. Do not make a short tourist product the only number attached to long-term banking.
How do we test broadband before signing a lease?
Ask for the exact provider and plan, run wired and Wi-Fi tests at work/school-call times, inspect router placement and mobile backup coverage, and check installation lead time, minimum term, relocation and cancellation charges.
Should the family use eSIMs?
They are useful for an arrival bridge and dual-number setup if devices support them. Confirm the plan can receive SMS, make local calls, be topped up and remain valid—not all travel data eSIMs provide a normal local number.
How can remote workers avoid an internet single point of failure?
Use fixed broadband plus a mobile provider with a genuinely different network path where possible, a charged power bank/UPS, hotspot-capable device and a tested alternate work location. Check employer security rules before using public Wi-Fi.
Can a child's SIM be registered in their own name?
Rules vary. In the Philippines, a minor's SIM is registered under the parent or guardian under the Act. Elsewhere, operator age and identity rules apply. Keep family numbers under truthful ownership with recovery access.
Will Netflix still work after moving to Southeast Asia?
Netflix can be used while travelling, but its official guidance says a permanent country move requires cancellation and a new sign-up in the destination. Price, billing currency, payment methods and catalogue can change. Preserve profiles and history through the supported account route where possible.
Should we change our Apple or Google account country before moving?
Usually wait until the family has audited balances, subscriptions, Family Sharing or Google family groups, essential apps and local payment requirements. Change one system at a time after arrival and keep recovery access working.
