Can You Buy a SIM Card for an Existing Cell Phone?
When you buy a new phone, you can usually transfer the SIM card from your old phone to the new one and keep your phone number.
Subscriber identity module (SIM) cards are essential for connecting your phone to a cellular network. They are small chips that are installed in cell phones to connect them to the carrier network and a specific user account (phone number). When you buy a new phone, you can usually transfer the SIM card from your old phone to the new one and keep your phone number.
While SIM cards are an excellent way to transfer data from old phones to new ones, can a new SIM card be purchased for an existing cell phone? It is determined by the type of phone.
GSM Mobile Phones
GSM phones are the most widely used worldwide. SIM cards are used to connect the device to the cellular network and the user’s account.
If your current phone uses GSM technology, you may be able to get a new SIM card for it. You simply need to ensure that it is “unlocked” first. Some carriers include software that connects the SIM card to the serial number of the phone. If the two do not match, the phone will not function. When you unlock a phone, that link is broken and you can use different SIM cards.
CDMA Mobile Phones
SIM cards are not used in these phones at all. They are instead linked to the carrier network and user account via built-in software that cannot be changed. In other words, they’re locked and unable to switch carriers. A new SIM card cannot be purchased if you own a CDMA phone. The only way to switch carriers is to have the device authenticated by the service provider directly.
How to Know Which Type of Phone You Have
Remove the SIM card from a friend’s phone and insert it into yours. If your phone does not have a SIM card slot, it is a CDMA device and you will be unable to purchase a new card. If it has a slot, swap the SIM cards and dial your friend’s phone number. If your phone rings (while using their SIM card), you have an unlocked GSM device and can get a new SIM card. If your phone does not ring, it must be unlocked before a new card can be purchased.

Then comes the first bill…
What exactly are these additional activation and SIM fees?
Activation and SIM fees, like baggage fees at the airport, are frequently included in the standard (yet unmentioned) cost of phone service.
To make matters worse, they don’t appear automatically when you start service. If you upgrade your phones or add a line to your plan, they will almost certainly appear on your bill again.
While you can sometimes request that your service provider waive these fees, most will not… you’re stuck paying.
