Your First Week in Bangkok: SIM Card, Banking & Address Registration
Walking out of Suvarnabhumi Airport into Bangkok's warm, humid air is the start of an exciting adventure. But once the initial excitement settles, you have a long checklist of practical tasks to complete during your first week. Getting these tasks done in the right order can save you hours of government bureaucracy and let you settle into your new life quickly. Here is your ultimate first-week survival guide.
In this guide:
- 1. 1. Day 0: Before You Land (TDAC Arrival Form)
- 2. 2. Day 1: Get Connected (SIM Card & Transit)
- 3. 3. Day 2: Navigating Transport (Ride-Hailing & Transit Apps)
- 4. 4. Day 3: Secure Your Address & TM30 Registration
- 5. 5. Day 5: Local Banking & QR Payments
- 6. 6. Day 6: Emergency Contacts & 7-Eleven Essentials
1. Day 0: Before You Land (TDAC Arrival Form)
Before you board your flight, make sure you complete the Thailand Digital Arrival Card (TDAC). This is a mandatory electronic entry form that replaces the old paper-based TM6 form. You must submit your travel details online within 72 hours prior to your arrival via the official government portal at https://tdac.immigration.go.th.
Submitting your details is completely free. Once completed, save the confirmation QR code on your phone or print it out, as you will need to present it at the immigration desk upon arrival.
2. Day 1: Get Connected (SIM Card & Transit)
Do not buy a tourist SIM card at the airport arrivals hall—they are overpriced and have data limits. Instead, visit any official AIS, True, or DTAC shop inside a shopping mall (like CentralWorld or Terminal 21) on your first day. Bring your passport and buy a monthly unlimited data plan for around ฿300 to ฿450.
Also, buy a Rabbit Card at the nearest BTS Skytrain station. This rechargeable card allows you to tap through the BTS gates quickly, saving you from queuing for tickets during rush hours.
3. Day 2: Navigating Transport (Ride-Hailing & Transit Apps)
Traffic in Bangkok can be overwhelming. On your second day, download Grab and Bolt, the two primary ride-hailing apps in Thailand. They allow you to book cars, taxis, and motorcycle taxis with upfront pricing, eliminating the need to negotiate with drivers. Link your international credit card to Grab for cash-free rides.
Additionally, download the 'ViaBus' app, which provides real-time GPS tracking for local buses, and the 'BKK Rail' app to plan your journeys across the expanding BTS Skytrain and MRT Subway networks.
4. Day 3: Secure Your Address & TM30 Registration
Once you sign a lease for your condo, your landlord must submit a TM30 form to Thai Immigration within 24 hours of your arrival. This form registers your address and is required to open a bank account, get a driving licence, or extend your visa.
Ask your landlord for a copy of the TM30 receipt (or the online registration screenshot) immediately. Keep this document printed inside your passport at all times.
5. Day 5: Local Banking & QR Payments
Take your passport, TM30 receipt, and lease agreement to a main bank branch (like Bangkok Bank's head office on Silom Road) to open a savings account. Ask for mobile banking access and a debit card.
Once set up, fund your account (using transfer services like Wise) and use the bank app to scan QR codes for payment. This is the national payment system (PromptPay)—it is accepted everywhere from street food carts to high-end malls, eliminating the need to carry cash.
6. Day 6: Emergency Contacts & 7-Eleven Essentials
To conclude your survival week, save key emergency numbers on your phone: dial 1155 for the Tourist Police (who speak English and handle tourist-related disputes), and 1669 for medical emergencies.
Finally, buy a rechargeable smart card at your local 7-Eleven. 7-Eleven is the center of daily convenience in Thailand, offering everything from fresh toasted sandwiches and coffee to SIM card top-ups, bills payment, and basic pharmacy items.
