    Since the blackjack was still less than a year old. ATT replaced it free of charge, but you have to go through all the support steps they ask you to undertake first. Including going to a store and having them swap your sim card.

    I am having the same problem with my Blackjack. It is about a year old, my husband gave me his old phone when he got the newest version. I had my SIM card from my Treo and I kept getting the "no SIM card" message and my phone would shut off during calls. I went to the AT&T store and the guy there told me that since my SIM card was from the Treo, it was not the right one, and that I needed a new card. He gave me one free of charge, but it is still doing the exact same thing. Hanging up on people, saying no SIM card. It is very frustrating!!!

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.

(solutions are already indicated).

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.


BenQSIEMENS JASB1A want another sim to operate wid instead aircel

i have this model benQ-SIEMENS JASB1A ....2 things it is locked and 2nd i don have any sim card right now ...but i want to operate with different simcard.. plz send me sim code

"Error 0" Samsung Blackjack. SIM card is missing or is not valid.

If he used it for the same carrier you are on (ie: sprint, AT&T, verizon, etc..) then it may just be a different format SIM card. Over my past 3 phones, I have had to change sim cards twice. Good thing is, usually the carrier doesn't charge for this. For example, if I took the sim out of my current LG g6, and tried to put it in my old galaxy note 3, it wouldn't work, I would have to get one of the older style SIM cards.
On the other hand, sometimes you won't be able to take a phone from one carrier to another, even if it is unlocked. It all depends on the cellular technology that the phone supports.
Hope this helps.

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

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.
