Question about Blue BLU Studio 5.5 D610A JB 4.2 Android GSM 3G US Unlocked Quad Core Phone
Your update, must have included a radio firmware update. I would try and contact blu support and ask them how to get old software back. Also you could try a factory reset. Also check apn settings, and make sure they are correct. One more thing, if it's only been happening for a short time, it could be your provider working on the tower.
