How do I extend the expiry date validity of my Thai SIM?

Updated September 7, 2026|Category General

Extend the validity of a Thai prepaid SIM

Keep your Thai prepaid SIM active by adding a validity package before it expires. Check your current expiry date first, then choose the package that gives you the number of days you need.

Thai SIM validity packages

Go to MobileTopup Thailand, choose your carrier (AIS, DTAC, or TrueMove H), then scroll to the bottom of the product list to find the validity packages:

$1.09
3 Months Validity
delivered in seconds
Top up
$2.19
6 Months Validity
delivered in seconds
Top up

Select the validity package you need, enter the Thai prepaid number you want to keep active, and complete the top-up. The carrier may apply a maximum validity period, so check your current expiry date before choosing a package.

Check your SIM expiry date

  • AIS: dial *121#
  • DTAC: dial *101*9#
  • TrueMove: dial #123#

Tourist SIMs

Tourist SIMs can have different validity limits from local prepaid SIMs. If your validity cannot be extended as expected, check the carrier app or contact the carrier's customer service for the rules that apply to your plan.
