Re: blackjack no sim card or simcard error

I had the same issue, cleaning the contacts on the sim card did not help. BUT i went and got a new SIM, it did the same thing.. till i wedged some folded up paper into the sim slot on TOP of the sim card forcing it closer to the contacts. So far this is working for me atleast. good luck.

Can't read sim card

Have you used this SIM card in another phone?

Some cell phones have trouble reading SIM cards that have been used in other phones. (Example: The Samsung Jack may not be able to read a SIM card that has been used in a previous Samsung BlackJack model.) I run in to this problem almost daily with my customers.

Your HTC phone probably has the same problem. To correct it, you'll need to purchase a new SIM card (you can get one on eBay for the least amount of money) and contact your cellular provider. Tell them you have a defective SIM - that you purchased a new SIM card and you need your account switched to the new SIM card.

After you give them your new SIM card number, it will take about 15 seconds and the new SIM will be ready to use in your HTC TyTN.

A message pops up saying: Invalid or missing sim card. You can still make emergency calls if your service provider supposrts it. I have a sim card in their but i guess it doesn't read it?? HELP ME PL

Is this phone from the same service provider as your simcard? If not, not all phones are unlocked to work with the sim cards of rival companies. If both the phone and sim card are from the sam company, then you can have the company replace your sim card. They usually do this for free as a courtesy as long as you explain the problem to them. Hope this helps

Sim locked

I did a search on how to do a factory reset.

This is how to reset the device itself. Follow the directions carefully or it won't work and heed any instructions, like removing any media cards.

Try that and let me know if it works, if not you can try reloading the OS, which is a bit more complicated, but I can help if it comes to that.

Good luck.

How to get the phone to be unlocked

you may have a bad sim card.take it back where you bought it ask them to check it out.usually the techs at the phone mart are pretty good about replacing your equipment if its faulty and make sure it works before you walk may get a new phone out of the deal.

No service

go to start
go to settings
go to more
then go to security
it should say device lock then under that it will say enable or disable sim lock if it says disable click that and type in 1234 then click done

that worked for mine

Blackjack sim card

Well, no. Your sim card must have taken a big jolt to it in order for it not to work. Simple, you need a new one. Got a Sams club near you? They should be able to give you one for free, att corporate stores charge 25.00. But sorry to say you need a new sim.
