How to Set Up Auto Top-Up for Your Mobile Phone in Thailand

Living in Thailand as an expat means adapting to local systems — and one of the most convenient habits to adopt is setting up auto top-up for your mobile SIM card. Whether you use your phone for work, video calls with family, or endless TikTok scrolls, forgetting to top up your data or balance can leave you disconnected at the worst time.

In this guide, we’ll show you how to set up auto top-up for your Thai mobile number — even if you’re using AIS, DTAC, or TrueMove H — with easy options for expats from India, the Philippines, and the United States.

Why Use Auto Top-Up?

Auto top-up saves time and prevents service disruptions. Here’s why it’s especially useful for expats:

• No more manually buying credit every few days

• No risk of losing mobile signal during urgent situations

• Great for maintaining long-term data plans

• Helps when you're traveling and can't find a nearby top-up point

If you’re using your mobile data as a backup internet connection, having an uninterrupted plan is essential — especially for remote workers or expats managing digital businesses.

What You Need to Set It Up

To enable auto top-up, you'll need:

1. A Thai SIM card from AIS, DTAC, or TrueMove H

2. A mobile app (myAIS, DTAC app, or True iService) installed on your smartphone

3. A payment method: Thai debit/credit card, PromptPay, or e-wallet (ShopeePay, TrueMoney, etc.)

4. A stable internet connection to register and verify payments

Most providers also accept international credit cards, though Thai-issued ones tend to be more reliable for recurring payments.

Setting Up Auto Top-Up with AIS

If you use AIS 1-2-Call, follow these steps:

1. Download and open the myAIS app

2. Log in with your AIS number

3. Go to “Top-Up” > Choose “Auto Top-Up”

4. Select the amount and frequency (e.g., 200 THB every 30 days)

5. Add a payment method (card or e-wallet)

6. Confirm and enable the feature

AIS will send you a notification before each auto-charge. You can change or cancel it anytime in the app.

Setting Up Auto Top-Up with DTAC

For DTAC users, here’s how to activate auto top-up:

1. Open the DTAC app

2. Tap on “Top-Up”

3. Choose “Auto Top-Up” or look for the “Manage Payment” section

4. Set your monthly amount (e.g., 150–300 THB)

5. Add your card or PromptPay account

6. Enable the schedule and confirm

DTAC also offers auto-renewal of internet packages, which you can activate after your top-up is completed.

Setting Up Auto Top-Up with TrueMove H

If you’re on TrueMove H, follow these steps:

1. Use the True iService app

2. Tap “Top-Up” > then select “Auto Top-Up”

3. Enter your preferred amount and schedule

4. Add payment via TrueMoney Wallet, credit card, or bank account

5. Confirm and activate

If you link your number to TrueMoney Wallet, you’ll also get bonus points or cashback for recurring payments.

ShopeePay and Lazada Wallet Options

If you top up through Shopee or Lazada, you can’t set up traditional auto top-up. But you can:

• Save your phone number and set reminders

• Use “Subscribe & Save” on some Shopee listings that send top-up vouchers monthly

• Enable ShopeePay Auto-Debit (beta feature in 2025)

These platforms are ideal if you like to browse promotions, but they don’t replace the official auto top-up systems.

Things to Watch Out For

• Check your package expiration — auto top-up won’t help if your SIM card or plan expires.

• Avoid overcharging — don’t set auto top-up for both data + balance at the same time unless needed.

• Monitor notifications — your provider will send alerts before charging.

• Test it once manually — to ensure your payment method works smoothly.

• Keep funds ready — e-wallet or card must have sufficient balance to process payments.

Is Auto Top-Up Safe?

Yes. All major providers in Thailand use secure payment gateways. Still, you should:

• Only set it up through official apps or websites

• Avoid third-party apps or links asking for personal banking info

• Enable two-factor authentication if your bank or e-wallet offers it

Summary

Setting up auto top-up for your Thai SIM card in 2025 is quick and easy — and can save you from the hassle of running out of data during an important video call or while traveling. Whether you’re an expat from India, the Philippines, or the US, the process is simple through AIS, DTAC, or TrueMove H’s apps.

It's one small change that offers big peace of mind.
