In many cases, an activation message will pop up once your SIM card is successfully registered. If not, you may need to wait for a while or contact the customer service team.

6. SIM Swap and Porting

If you are switching numbers or transferring your number from one network to another, a SIM check is crucial. You will need to make sure the SIM swap is completed successfully to avoid losing your number. Some networks also require a formal verification process to ensure that the SIM card is activated in your name.
