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

I wish. He does not have the key for that as of yet.

 That reminds me I have to get my money back from one of these companies that try to do it but I wasn't successful.

As of now, I ordered two walmart phones and hoping it's compatible with T-Mobile, while the Verizon I'm working on to unlock for. Decent price.

I have the Alcatel Smartflip from Cricket.
They gave me the unlock code (after 6 months of using the phone) but I can't figure out how to enter the code.
When I put a different SIM card in the phone, I get a quick message "Network Sim is Locked" which goes away after 1 second.
Any help appreciated.
Thanks.

Thank you.
I may have to use him.
But preferably I'd rather do it myself & for free since I was given the unlock code.
Any ideas on doing it myself?

Wherever you got it from ask them how to input the unlocking code.

Got it from Cricket.
They keep on saying that after putting in a different SIM I'll be prompted to enter the unlock code and they have no idea why I'm having the above issue.

Just saw this here:
https://sites.google.com/view/bananahackers/devices/alcatel-4052rcwz
*****
Only some models of the Alcatel OT-4044 series (including Alcatel Cingular Flip 2) are enabled for debugging, while other variants of the same series are blocked just like Alcatel A405DL MyFlip and the newer SMARTFLIP / Go Flip 3.
It therefore appears that by default all new KaiOS phones sold in the United States are always and irreparably blocked by the manufacturer, just like the Doro 7050, depriving aspiring US developers of the opportunity to participate in the experimentation and learn how the KaiOS ecosystem works.
*****
Does that mean my phone can't be unlocked - no matter what?

I've played around in the past, even after sticking in another sim card it just said SIM card error and it didn't read the SIM card.

  You can bring the phone into it's boot/ recovery mode by [9/7/2020, 2:30 PM] eBay Unlock Code: turn off the phone
[9/7/2020, 2:30 PM] eBay Unlock Code: then hold volume up and down and connect to pc
[9/7/2020, 2:30 PM] eBay Unlock Code: when show warning then press volume up, and it will show blank screen.

 Took him 3 minutes and paid him $4.
 Connected the device to a pc and all done. I tried to follow what he did, but seems he has a code and program which he uses to unlock it.

Will that fellow not charge if he's unsuccessful?
Also, how can he be contacted by someone with WhatsApp?

You mean without what'sApp?

 Connect it to a computer and I'll help you with the process, can see when he's avlb.
 You would need teamviewer or anydesk.

 Would cost $5.

 Or you can buy from eBay and then message him from there, and be in contact with him when works. Takes 3-6 min. And yes will refund I'm sure if it doesn't work.
 I only paid him after he did the unlock. Or maybe that was for the other few after I bought from him already.

 If you pay $150 to unlock then yes.

 Just curious what's with Verizon service that you don't want to use tracfone service?
