Long sob story version:
Been waiting and looking for an update to my Xperia Pro, wanted a good QWERTY slider Android. Unfortunately, manufacturers think there's no market for it just because they kept releasing **** spec versions, so obviously people won't buy em. =\.. all in all, had no choice but to pick up the best out there spec wise, the Droid 4 from the USA through eBay as it has the specs to work globally.
First issue unfortunately was not being able to get data connection. That is fine, as I can use WiFi for now until I figure it out.
But the main issue is with calls/sms!
When the phone first boots, obviously there's the warning about "This SIM card is from an unknown source".
Once booted, I am unable to receive any calls. Any calls made to that phone will immediately be sent to Voice mail. Doesn't matter if the phone is awake or in sleep.
Now here is the funny thing, ONCE I send out a SMS or make a call, I can start receiving calls. Unfortunately, this is also short lived as after an undetermined period of time, the issue will pop up again and I won't be able to receive any calls or even SMS.
As it sometime works and sometimes does not, this gets really frustrating as I can't pin point what exactly is the problem here.
I could use the help and advises of the gurus here and this is really infuriating to me.
Thank you very much everyone for taking the time to read and assist me on this issue.
