It sounds like your phone is locked to a specific network (not the network for your SIM card). You might need to get it unlocked before you can use the SIM you have.
You have to get a new sim card or you put more money onto the card
my phone says sim barred when i try to send a text
BEST ANSWER: IF you entered a wrong PUK code 3 times you disabled you phone and the sim card is no longer valid. You don't have to throw away your phone as previously noted. Yeah you could and upgrade if you want but if you want to keep the phone, do it and look for the punch out card that the phone's sim card came with. On it will have the phone's PUK number on it. Enter it and you phone will no longer be disabled. The other option is to contact customer service or go into a reseller of Tracfones and explain what happened and they would be able to look up your PUK number for you or in some cases the retailer may simply give you a new SIM card, however a cost may be involved, roughly $5. Yes, look for your punch out card, or contact customer service. Avoid the fee.d PRIOR ANSWER: >>Call them and get a new sim card if it's under a year old. If it's over, toss it. It's defected.
It means that your phone is registering your sim card,which is slotted in the back of your phone near the battery {cell},and look in the dictionary for registering because i cannot explain it.
If your cell phone has a sim card, your phone may say out of service if you are far from a town or city. A phone needs a cell tower to work, so you may get an out of service message if you are not close to cell tower.
