What happens after the 4 weeks of the free Smart Unlimited Plus bundle are over?

When your free Smart Unlimited Plus bundle finishes, you have two choices. You can either continue using the same bundle or you can switch to Smart Unlimited, which features unlimited data only if you prefer. The process is simple – just open the GO app and select the new bundle you fancy. Alternatively, send an SMS to 16410 with the code of the bundle you want to activate.
