Changing your prepaid SIM card provider is not a daunting task. While changing your service provider, do not cancel your existing service as, in this case, you won’t be able to port your current number. You only need to find a plan that suits your requirements and order a new SIM online, on the phone, or can even buy it from a store.
In the sign-up process, you can mention if you wish to transfer your existing number to the new connection. To do so, you only require to specify your phone number and the service provider. Once you receive the new SIM, active it, and this begins the process of transfer of number. One thing that you need to note here is that your previous service will continue until the whole transfer process is not completed.
