Topic Wiki

I think there is a big misunderstanding what locked/unlocked means.

All phones that are made are always assigned to a carrier (yes even the ones that say "Factory GSM Unlocked") to prove that just look up the model of the phone and you will see what carrier it was assigned to.

In order for a phone to have service the company has to know that you want service on this phone.

In the past company's like Sprint and Verizon did not work with a sim card they worked with the id of the phone to recognize what kind of phone / what carrier it was assigned to. This is know as CDMA. Yet company's like att/t-mobile did that too but the service was applied by using a sim.

Once LTE came out for what ever reason all company switched to the "Sim technology". There is still one thing that did not change, each carrier has their assigned bands that they have from the FCC that they are allowed to use.

Being that there are standard bands that every one uses (for international or the like) these are included in every phone. So.... All verizon phones will work on att, BUT will only have the bands for slower internet since those are standard bands.

Now verizon's LTE band is NOT a standard nor is their CDMA a standard so an att or a t-mobile phone will NOT be able to accept a Verizon sim.

Now lets go to sprint phones,

All other company's when they had the phones made for them all they do is have it customized for its own use (Read: their own LTE bands). Sprint on the other hand not only did they have them customize it they put a lock in the software blocking all local USA bands (Verizon ATT and Tmobile).

They even go a step farther and they still do the old way of checking the device ID to see if its a sprint phone or not.

Hope this explains a few things feel free to ask any questions.

Att has an easy way to ask for an unlock https://att.com/deviceunlock

How to check a Sprint iPhone (only): You cannot check it with an american sim you must put in a foreign sim. You DO NOT have to backup and restore as sprint sends in the email! Connect to wifi before starting this procedure.

When you put the sim in one of 3 things will happen.
1. It will say no service in the top right corner = Unlocked
2. It will do a soft restart and ask you for your apple id password = Almost unlocked, after putting in the password its unlocked
3. It will do a soft restart and say "Sim not valid" = Phone is locked

If you got number 2. and you dont know the password just put in your old sim and all will return. When you find out the password repeat the steps.

Willmyphonework.net Can check if the phone will work

there are some phones that are CDMA and GSM compatible not all are
Check if its a "world phone" or "global ready" many higher end ones nowadays are.

Once I get the unlocked code for my S4 Active do I just put in the Sim card and put in the code or I still have to do something else?

Does anyone know if it's worth even looking into unlocking my Lumia 520 (at&t gophone, but being used on a regular plan)? I am thinking of switching to Sprint by adding a line to my wife's account. I am getting conflicting reports about whether the phone would work on Sprint after being unlocked.
I bought the Lumia on sale from Amazon a couple months ago. Until then, I had a basic messaging phone. Once I switched phones, AT&T started charging me an extra $20/mo with absolutely no change in service. Basically taxing me for doing something independently with my money.

It won't work on Sprint. They have a Lumia 625 I believe for Sprint that can be had at a decent rate.

thanks, but im not sure how comfortable i am giving a random guy access to my phone via remote connection
I know people that have done that no problem. What is the concern? Just back it up, and then worst case scenario if he is looking at your personal info or whatever, just sever the connection.

I wouldnt worry, you can see whatever he is doing. If you really are concerned, just have him connect to a computer that you dont generally dont use for sensitive info banking etc...

if you see him going where he shouldn't then disconnect the session
I wonder what people who type "u" instead of "you" do with all their free time.

I don't know anything about him. Friends of mine have used similar services in the past without incident.

But I see this too
