Extending SIM Card Usage in Thailand
Overview
Traveling to Thailand multiple times a year, I’ve found that using a local SIM card significantly cuts down on time and costs. Local calls are extremely cheap, and calls back to the U.S. won’t break the bank either.
Essentials
To take advantage of this, all you need is an unlocked GSM tri-band or quad-band phone and a Thai SIM card. The SIM card, a small chip under your phone's battery, contains your subscriber identity.
You can find SIM cards in nearly any country, and swapping them is quick and easy.
Unlocking Your Phone
In the U.S., carriers tend to lock SIM cards to specific networks. However, unlocking your phone is relatively inexpensive and straightforward. You can try asking your provider to unlock it, but often you need a strong case or be a long-term customer.
A simpler solution is to buy an inexpensive, unlocked phone in Asia. Both new and second-hand options are affordable and readily available.
Maintaining Your Thai Number
One challenge is keeping the same Thai number for multiple trips. After obtaining a SIM, you add credit by purchasing a phone card at a local 7-11 or Family Mart. Scratch off the coating to reveal a code, enter it into your phone, and the value is added to your SIM. This also extends the SIM's validity.
In Thailand, adding 300 Baht (about $9) grants an extra month of usage. Since my trips can be three to six months apart, I need to ensure my SIM remains active.
Extending SIM Validity
This trip, I discovered a solution. I use a service called 1-2-Call. If someone else has extra validity months, they can transfer them to your SIM.
My girlfriend had months to spare, so she called *140 and followed the instructions to transfer the time?"one month at a time?"to my SIM. It took just minutes, and you can choose English or Thai for the prompts. Remember, “validity” refers to how long the card is active.
Sharing Credit
I also learned I could swap credit between our phones. I often pre-loaded my phone with about 1,000 Baht to ensure enough validity for my next trip.
Previously, I purchased cards for her to have time and credit to call me in the U.S. Now, she receives added credit, and I gain time?"a perfect win-win.
Conclusion
Using a local SIM card in Thailand not only saves money but also offers flexibility. By sharing time and credit, you can maintain your Thai number effortlessly between trips and enjoy smoother, more economical communication.
