If you plan on visiting Thailand any time soon, don’t take off without a prepaid SIM card. The Thailand SIM card provides a simple, convenient, and affordable way for any traveler to make and receive those all-important calls while abroad.

The prepaid SIM card for Thailand is a practical option for using your existing world phone as a prepaid Thailand cell phone while you’re in the country at a better rate than you’d pay for a Thailand cell phone rental. It’s also a trouble-free ticket to using the same options that the Thai themselves use—the local Thai cell phone system. The SIM chip, combined with an unlocked GSM World cell phone, helps you keep the lines of communication open without being burdened by high international roaming surcharges applicable when you use your “home” SIM card abroad. You’ll likewise enjoy the benefit of SMS text messaging, voicemail, MMS, GPRS, a local cell phone number in Thailand, and FREE incoming calls. The prepaid feature gives you complete control over your costs, and with our low domestic and international calling rates, having a cell phone in Thailand is affordable for all. Access to customer service from your Thailand cellular phone is available 24 hour a day, so you’ll always have assistance with any unexpected issues or questions about your calls. No yearly contract, monthly charges, or credit check is involved.

Your Thailand SIM Card will require a SIM-unlocked GSM cell phone that supports the 900 and 1800 frequencies. If you do not have your own international cell phone, we have several models available for your consideration. . Please click here for more information.
