I solved this issue for one of my customers . Here were our steps:
Options > Network & Connections > Mobile Network > Network Technology should be sent to 1xEV.
As soon as we switched it back the SOS disappeared. SMS started incoming immediately and voice tests were successful!

Which email service?
There should be a "Can't access your account?" or "Need help?" or similar link on the sign-in page.

  • I am reluctant to post the procedure on how to get a password-Locked phone operational again, especially if it is a Blackberry. This will enable cell phone thieves to open password-locked blackberry handsets. To distance myself from this, I would recommend that you take the handset back to your service provider - if purchased at a cell phone shop, then take it back there. if you bought it from someone, take it back to that person/s. Last resort is to contact RIM who is the official Blackberry Manufacturer and support. Tell them your problem and they will take it from there. www.blackberry.com
My apologies but I cannot leave instructions on how to unlock a password locked phone.

HI is your blackberry mobile is asking for network lock password or code once you insert your sim in it then it mean the phone is locked to some other network provider due to this it wont accept any other GSM sim until you unlock it ..You can easily unlock your blackberry phone through online providers like UnBBLock.com here they are rendering network unlock code for all blackberry mobile models at reliable cost .You first check that whether the code is available for your mobile model ,country and network provider .If yes then pay for it and unlock the phone then freely use it with any GSM sim ...

Hi Michelle. I have the same phone and it happened to me a few times. On most phones the battery swells up when it reaches it's charging life end. In the 9720 the battery can still LOOK okay even though it might have reached its life-span. I eventually purchased a new battery, and wholaa, problem solved. A piece of additional advice is: Do not chat with you phone on the charger. Unplug the charger when battery is fully charged: We tend to charge the phone anytime and every time before we go to work or somewhere - you have to let the battery run flat on its own at least once a month, then start a fresh charge from fully flat to fully charged. This will prolong battery life. I a new battery does not solve the problem, have the charging pin checked out. Alternately if you know someone that has the same handset as you, ask them to stick your battery into their handset and visa versa. Hope this info help :)

If it is not available in the BB store(its not) then you need to search for the apk on the internet which you may not find, and if As long as they support android 4.3, it will run on your device with some glitches. that means you need to have 4.3 running on your device. it may be possible however may not be worth what you have to go thru to MAYBE be able to use a crummy version of it. Best of luck
