I needed to transfer my cellphone number of choice from a Alcatel to a Samsung 8 plus phone, and it worked like a charm.

as advertised, mobile sim kit, works as expected and easy to setup.

This SIM KIT is what you need to transfer your own phone to Net 10 and a no contract plan. The SIM KIT is fine, but it took a long time to get the number transferred from a burner phone, which was already on a Net 10 buy minutes and time as you go plan, to a new iphone with a monthly no contract plan. We were transferred to three or four different agents, and after about two hours of supplying the same information (IMEI #, etc.), the new phone was finally activated with the same number. Possibly, if we weren't trying to transfer the number from a burner phone or if we were willing to take a new number, the process may have gone faster and easier. The SIM KIT contains sim cards from Verizon, AT&T, and T-Mobile; so there are options to pick your own carrier as long as your phone is compatible. We have been using Net 10 with the burner phone for years and have had very little trouble with it as far as coverage, etc. We haven't used the new iphone very much since we just had it set up a short time ago; so we can't speak to coverage, etc., as we haven't traveled away from home as yet.

For a buck, you can't get much better. The Big 4 try to charge you $25+ for SIM cards. Net10 service provides the exact same coverage as the Big 4, with the ease of choosing which provider works for you and your phone at the same company. Easily switch to a different network when your needs or phone change. Be sure your phone is compatible with the network you choose. Net10 prices are very reasonable, and you can often find discounted refills on e Bay. I recommend Net10 for users who need Verizon or AT&T for the best bang for your buck (Tmobile and Sprint have plenty of other MVNOs that are cheaper than Net10).

Good inexpensive SIM card for GSM type phone, such as Safelink and Net10.
