I have the Alcatel A851L that was sent to me by straight talk when my S3 kept messing up. I can't seem to update my software os. Every time I click on check for updates I receive the error l"server not reachable". I am planning on buying a new phone the Orbic Slim Unlocked Phone. It has Quad Band GSM 850/900/1800/1900MHz; Tri-band UMTS (II, IV, V); Quad Band 4G LTE (2, 4, 5, 17). MT6735 1.3GHz quad-core processor and Mali T720 GPU.
5" HD IPS TFT LCD with DragonTrail glass; 13MP AF Rear Camera with flash/5MP FF Front Camera. 16GB memory + 1GB RAM; microSD up to 128GB; 2200mAh Li-Ion battery. Dual SIM (1 micro/1 nano).
Compatible with US GSM Networks including T-Mobile, Metro PCS, AT&T, Cricket, Straight Talk and others. Will I be able to upgrade the os on the new phone to marshmallow 6.0?
