Mobile Signal goes off and turns back on every 2 seconds
Here is my problem. I have a blackberry Key2 silver.
sometimes i no longer get audible alerts. so i cycle the power down and things go back to normal.
well this morning i did that and when it powered back up i kept getting a repeating alert that i had voice mail. this is because the phone kept reconnecting to the cell signal and then losing a signal over and over again.
when i pulled my sim card out. no problem. phone is normal. and the battery is not draining due to the constant signal going in and out.
i put the sim back in. problem comes back.
i am a light user. ive only downloaded 5 additional apps outside of the factory apps. Netguard, confide, musicolet accubattery and Xodo.
i disabled netguard and powered it down . when power resumed the problem was still there.
i went to t-mobile store. and got brand new sim card. i swapped out the old sim for the new sim. same problem.
i am at a lost. this was very sudden. the phone had zero problems until this morning when this started.
any ideas ?
