$2.99 Amazon Sprint SIM card kit review
If you want to sign up for Sprint service either directly from Sprint, or from a Sprint MVNO (mobile virtual network operator) like Tello, you'll need a Sprint-capable (CDMA) phone as well as the correct model Sprint sim card. If you buy a phone from Sprint (or the MVNO like Tello), the phone should include a Sprint sim card, but if you want to buy your own phone or if you want to use your own existing phone (referred to as BYOD or bring-your-own-device), you need to make sure your phone is "Sprint capable" (i.e. supports CDMA) and you will also need a Sprint sim card. Unlike GSM sims (i.e. AT&T / TMobile) where you only need to worry about the sim size (normal, micro, or nano size), with Sprint you need to get the correct model sim card for the phone you have. This can be a bit of a pain. The good news is that unlike GSM sim cards which can only be activated and used once and which then no longer work after service is cancelled, a Sprint sim can be used over and over again, so once you have it, it will always work, even if you previously cancelled your service or if you want to switch Sprint MVNO providers.
IMPORTANT: Remember that for Sprint, you need to get the correct model number Sprint sim... my Moto G4 used a SIMGLW446C or a SIMOLW506TQ, while my Moto G6 uses a SIMOLW416Q. As you can see, sometimes a phone like my G4 might have two Sprint sim model numbers available and either will work. But the SIMGLW446C will not work for the Moto G6 and the SIMOLW416Q will not work for the Moto G4. So find out which Sprint sim model you need for your specific phone and make sure you get the correct sim model!
What Sprint sim card model do you need? The easiest way to determine what Sprint sim card model number you need is to use the Tello Mobile phone checker here. Enter your phone serial number and it will tell you if your phone will work on Tello (Sprint) and it will ask you if you need a sim card. If you say yes, it will tell you the model number you need (you can then buy the sim from Tello for $10 if you want). If the sim model you need is: SIMOLW506TQ, SIMOLW416Q, SIMOLW506C, or SIMOLW516TQ, you can buy the Sprint sim card kit for $2.99 on Amazon which includes all four sim cards.
As stated above, the Amazon Sprint sim card kit includes different four sim cards (SIMOLW506TQ, SIMOLW416Q, SIMOLW506C and SIMOLW516TQ), and you just use the correct sim card for your phone. Just make sure your phone uses one of these four sim cards, and not a different model Sprint sim card. I've listed the four included sim models and some of the phones they work on. They may also work for other phones not listed.
