How To Unlock Your Samsung Galaxy S5 sim network

The Samsung Galaxy S5 is widely considered one of the best

 Android devices to ever hit the market.While initial sales weren’t
 quite up to Samsung’s expectations, they still moved over 12 million
units within the first three months of launch and that’s nothing to sneeze
at. Glowing reviews come, in part, thanks to the gorgeous display, powerful
 specs, and dust/water-proofing.
In fact, Consumer Reports recently recommended the S5 over Samsung’s
 latest offering, the Galaxy S6, citing the latter of these features as the impetus
for giving the edge to an older generation model. With this positive praise, expect
 to see many folks picking up an S5 used or at a bargain price upgrade.
With the upgrades, or even new contracts, you’re going to run in to the dreaded
 SIM lock dilemma. Any device purchased from one of the major carriers is going
to come restricted to their network. That means you’re not going to be able to take
 that AT&T device and run to T-Mobile for a discounted rate plan.
While this may be a more frequent problem for the jet-setters among us, that also
means you’re going to run into major headaches trying to use a prepaid SIM card
 when travelling internationally.
So, your choices are to stay with Carrier X and pay whatever rate plans they wish
to offer, regardless of competition, or be stuck with a $600 brick. Don’t care for that
option? Yeah, we didn’t think so.
Luckily, you can SIM unlock your Samsung Galaxy S5 for free through your service
 provider – as long as you meet their criteria (the phone paid in full and isn’t tied to a
 contract). Everyone else will need to use a service like Android SIM Unlock to buy
an unlock code for their phone.

Carrier Unlock

You’ll need:

• Your IMEI number. This can be found by navigating to Settings -> More -> 
• About device -> Status or by dialing #06#
• Your carrier’s Customer Service number. If your carrier isn’t listed below, 
• Customer Service is usually preloaded in your phone’s contacts as 611, *611
•  or similar variation.
  • T-Mobile: 1-877-453-1304
  • AT&T: 1-800-331-0500
  • Sprint: 1-866-866-7509
  • Verizon: 1-800-922-0204

The simplest, and least expensive, course of action is to simply call your carrier and
 request the unlock code. Bear in mind that it could be a little tough; Carrier X doesn’t
 want to lose out on your business. If your service provider grants your request it will
usually e-mail your unlock code within a few days. Have this code ready as you’ll be
 prompted when entering another carrier’s SIM card.
SIM Unlocking your Samsung Galaxy S5 is a rather painless process. Here’s a 5-step
 process to help you out.
