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.

You phone fails to recognize,the a look at this causes,might 1 of the problem is listed below.
(solutions are already indicated).
* your simcard might be corroded and need to be clean using a pencil eraser. * simcard socket lock might be losen and need to bend a little bit downward to reach the contact of the simcard. * simcard reader or terminal pins is dislocated and not properly align,need to fix in proportion or re-aligning. * simcard reader or terminal and its pin is corroded and need to be clean using any rust solution and a cotton.
If the above method does not work,simcard IC might be damage and need a parts replacement,by this time,you need to bring it to the service center to fix this problem.
hi, check your sim card first ,clean it...next step is clean your simcard interface by eraser or lacquer thinner ...if still not works ,the sim card driver of your phone is need to replace..this simcard driver is small chips that makes the simcard working ,if it is damage the simcard interface did not recognized the simcard...if the first and second solution not works ,go to a cellphone repair shop to change your sim card driver... i hope it will help you..thanks
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.
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.
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
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 away........you may get a new phone out of the deal.
