If your existing phone uses GSM technology, there's a good chance you can purchase a new SIM card for it. You just need to make sure it's “unlocked” first. Some carriers include software that links the SIM card to the phone's serial number. If the two don't match, the phone won't work.2020-09-15
Where do you get a new SIM card from?
For lost SIM cards, you can order a new one on your service provider's site. Some companies require you to call their customer support directly or pick up a new SIM in-store. If your mobile provider has a physical store, picking up a SIM card is usually handled for free.
Can I just purchase a SIM card?
You can buy SIM cards directly from a carrier like T-Mobile or online from any retailer that sells electronics. SIM cards can also vary in size, depending on the model of the phone.2018-12-03
