Best Answer: Your current phone must be compatible with a new network and unlocked. You must port your number to the new carrier in order to keep your number. You should not cancel your old account before the porting is complete.
Which carrier should I switch to?
While there are many great plans for cell phones, the main thing is the network. If you are unable to use your phone plan everywhere you go, it is not worth signing up.
Although all the carriers have made great strides to ensure they provide service in rural areas, there are still some areas that prefer one carrier. T-Mobile's 5G network is the strongest, but Verizon and AT&T have better coverage in rural areas. To be certain, you will need to review the coverage maps of AT&T, T-Mobile and Verizon before you sign up.
An MVNO is a good option if you don't like the plans or network of a carrier. The best MVNOs will save you money by removing unnecessary features and services and offering a simpler phone plan. If you are certain that you will need T-Mobile or Verizon network, an MVNO can be based on either T-Mobile or Verizon.
I want my phone to be safe
If you don't owe any money, you may be able to bring your phone after you have learned how to switch carriers. You can have your best Android phone unlocked and it will likely work on your new network.
Many new phones can be used with multiple carriers. This means that you only need to swap SIM cards to connect to another network. After checking if your phone is compatible with a new network, make sure that the phone has been fully charged and unlocked. To activate your phone on certain networks, you will need your PIN or account password.
Verify compatibility with BYOD
First, make sure your phone is compatible with your new network. Although most phones work with almost every carrier now, there are a few older models that won't work on other carriers, particularly those made for Verizon or Sprint. You should make sure that you check your phone with the preferred carrier. Otherwise, you could be forced to trade in your phone and lose value. To check your phone, you'll need your IMEI number. This number can be found in the settings section of your phone.
All major carriers are open to you bringing a 5G smartphone as long as your plan supports it. Also, make sure that you have a compatible phone with the 5G bands.
