Carrier Unlocking a Samsung Galaxy S4 in only 5 Minutes

Do you cherish your telephone, yet not your administration supplier? That is the thing that happened to my lady friend, who has been limping by with moderate and spotty administration from our corner of Los Angeles. When she redesigned her telephone to the new Samsung Galaxy S4 she recognized she wasn't getting a serviceable or dependable association, if for voice or information. It was a great opportunity to switch arrange suppliers, without acquiring another telephone. Anyway first I would have done well to open her unit so she could do the switch...



The Samsung Galaxy S4 is one of the best Android cell phones as of now accessible, yet on our nearby T-Mobile system we discovered the whip-quick specs hampered by carriage moderate system speeds (note: the system rates could be uncontrollably distinctive only a couple of miles over, contingent upon particular system area and client load). Emily perceived I was once in a while harassed with the same issues as an At&t Wireless subscriber, as we live close by one of their recieving wires; she chose to take care of business and pay the additional $10/month to switch systems (luckily she wasn't bound by an agreement).

The T-Mobile Galaxy S4 model (Sgh-M919) is good with At&t's system, and once bearer opened might be enacted to use as an At&t apparatus (just admonition: sans Lte system). Bearer opening the telephone opens up system supplier choices, as well as on the off chance that you choose to offer your telephone, opened mechanisms offer less demanding and at higher costs.

I uncovered this simple to execute set of directions over at Xda Developers, permitting any T-Mobile Galaxy S4 possessor to open their unit without the need to dig at present establishing the telephone or change through programming; everything is carried out effectively through the inherent Android menu screens, scarcely more intricate than inputting the Contra code:
