I just got Microsoft Lumia 550 4G Windows 10 cell telephone only a couple of days back and I had been utilizing it with no issue : )
Anyway you gotta do a few things first for the smooth working for this mob.phone: 1. redesign the telephone programming projects completely utilizing a decent Wi-Fi association then 2. introduce all other key downloading so as to programme projects as you need them from the Store. Presently you arrive content with your MS Lumia 550 working bravo. Cheerful : )
