I have a t-mobile dash with WM6, and it is simlocked, is there any program or method to sim unlock the phone? DIY
thanks
Call T-Mobile and request an unlock code.
or you can download this SDA unlock... you can find the program if you google it man... it should not be hard to do so...
you wont find a free SIM unlocker (yet) unless you go through T-Mobile. The SDA unlock is for application unlock, it will not SIM unlock.
I try SDA unlock is not working, so how would i be able to get unlock code from t-mobile? thanks
what do i need to give them? receipt, bill., prove of purchase?
i did it, call the t-mobile company saying that i need to unlock the phone for oversea use, give them IMEI and email, two days later they email me back the code. Question is the code unlock both sim and cid, or just sim, how would i be able to check whether it is CID unlock? thanks
When you called T-Mobile, did they ask for a phone number or any kind of account numbers? I don't have a T-mobile phone number, so calling them for the code may be a problem.
you have to be t-mobile account holder, if you don't have one get a friend who use t-mobile to call for you. They will not ask you anything much (saying you are going oversea and want to use the phone there), just your email and phone IMEI.
Hi,
1. I bought a Samsung s4 mini SGH-I257M, locked by Telus.
2. I tried install super root, but each time it tried to launch the application, a shield from up-left corner will block it to run.
3. I asked a mobile shop unlocked for me with Z3X, but the sim card cannot be registered (the sim card is not from Telus.) Every time when the phone try to register the sim card to network, there is a small shield icon will shows in the up-left corner and blocks it.
4 After two days, I went to the shop and got my phone back. I rooted my phone with Root Dashi, a chinese root software. It works! I inserted a Fido sim, the shield no longer there, but I still cannot register my phone to the network. Any idea?
Sorry for my English.

Rooting and carrier unlock are not the same thing. it sounds like you do not have an APN for Fido or slightly possible the shop was not successful, but if so the Fido SIM should prompt the phone to ask for an unlock code.
If so, there are tons of outfits that offer carrier/provider unlocking. You can Google the string "carrier unlock SGH-I257M". You will find How to videos on YouTube regarding unlocking as well.
But likely it is just a lack of an Fido APN not allowing it to register on the repeater. I looked for the APN BTW, No luck.
You might also do some XDA searches on Chinese online Rooting. The XDA Developer Arco68 has an excellent method that works very well on your phone if you should loose the root you have.

What do you mean "do some XDA search on Chinese online Rooting".
Should I ask Arco68 and see is there a i257m ROM for me?
When I power on my phone with Fido SIM card, it won't ask for unlock code any more. Where I can get the APN setting?

There are several threads on XDA about Chinese online rooting, it has been found that IMEI's, personal data and so forth have been transmitted to the host servers in the rooting process and links on XDA (wisely) have been banned until the matter has been fully researched. There is a good search function on these forums. You can find info.
Asking a developer for a specific ROM is bad form, just asking generaly in the Q&A section in will net what you are seeking. The Dev's are not paid, they donate serious work to the community as a whole, Read the forums for the i9195's, those are the ROMs available right now.
Read up on APN's, locate Fido users, call fido, do research. Anyway, hope some of that helps, it's about all I know about Fido. Learning with some effort is well worth the time spent. No one is born knowing this.

Hi Systwk,
Thank you! Actually I use Chatr, not Fido. Because I don't want damage my current SIM card (cut to micro), so I use FIDO sim card which is currently not in use to test my phone. I got my SIM adapter today. I cut my Chatr SIM card and tested with my phone. It says registered on network, but the notification on the main screen says ?Selected network(chatr) unavailable", and I cannot make any calls. When I choose "Select automatically", it will say "unable to connect, try later".
Do you have any idea?
BTW, I tried with APN FIDO, it's not work.

farewellartist's suggestion is a good one. It could help to see what is going on. That aside, you have to use an APN that matches the network you intend to use and the account has to be active. Also the network protocol set on auto shows it finds the Network, the Sim and phone can connect, but it also needs to know how to communicate with it to register on the system. That's possibly the issue.
You really may find some help calling your Providers tech support regarding connection. Yes, that about as fun as banging your toes with a hammer, but usually has better results. It may be as simple now as plunging in an Access Point Name, user name and password in the APN. (Some Pre-Pay acct's use user and Password) Good news is you DO have connectivity. It's now down to details.
Keep plugging along, you are making progress.
Here is the support link for their Pre-Pay. I'm in Florida so I'm clueless regards to who you are dealing with.

Hope that helps you some.

The shied is gone after I took back my phone from a mobile shop. I rooted my phone and deleted the knox.

You are certainly not weak on signal. As long as you have the APN set at 'APN: chatrweb.apn' you should register.
Rare as it is, Bad SIMS happen. (Murphys Law). Just to rule out you can try the below and I Know the steps getting there are not needed, but it's for others in the future who may be newer at this:
To check connection at the base level try the following.
GoTo: Settings-Connections-Network connections-More networks-Wireless and networks-Mobile Networks-Network Mode, THEN start ticking the 4 setting starting with GSM only, and work upwards. It can't hurt.
Also when trying to connect with chatr, in the search for Network operators/Available Networks in mobile Networks, when it's done searching nets available, choose one chatr. not auto. If it finds two chatr towers try each.
I'm adding the chatr APN for anyone in the future as well. I assume you have the same but it's not in the screenshots.
You must be frustrated by now, hope someone else with experience on chatr can offer a fix. I assume you did get on either Telus or Bell so you know the thing connects, a replacement SIM is the last option I can think of.
Good Luck.............

Hi Systwk,

If it were me I would not re-flash anything. The connection problem would not likely be from a carrier unlock. Also it is not likely it would be from rooting or installing the CWM boot loader.
You have a known system now, you know when it worked, and you know the few modifications you have done. Even if you have called Chatr tech support before, it might help to call again and tell them it will not log on to their system. DO NOT tell them you have rooted the phone, DO NOT tell them you installed a boot loader. If you do that, they will probably say that is the problem, END of support. Just say it was unlocked by a dealer and now takes their SIM but it won't work.
They should walk you through each step of the configuration, they want your money every month, you want their service. Good place to start. Give them your IMEI, make sure it's good and not 'blocked'. it's in the settings/about device/status or dial *#06#. I'm assuming you already have confirmed your phone is comparable with chatr, I think you mentioned it was from TELUS, but with BELL, ROGERS or whatever, unlocking does not guarantee the Modem is the same as the new network you are trying to use.. There are several other reasons, but SIM, IMEI and improper configuration are the most likely problems if compatible.
There is a chance it is something simple that has been missed. You have shown patience, that is a big plus with modding phones. Going step by step and being willing to start over is something many here have done, and many times. Small problems are sometime the easiest to miss. So Call Chatr tech support, if they have an outlet near you maybe you can get a replacement SIM from them, (I would check that first) as I mentioned before.
One other thing to try, see if you can get a new Pre-Pay/month to month SIM from TELUS or the original carrier the phone was branded for. It should work and if not, they know their configuration. I'm out of suggestions, hopefully someone from Canada can be of more help. Don't give up. There are always answers.
Thank you, Systwk
The SIM card works with my old phone, so probably is not the SIM card problem. I take out the SIM card from S4 mini and power on it, the signal still shows good. So, I think flash ROM is the most simple way for me. Anyway, I will can chatr on Monday.
Hi Systwk, I called Chatr just now. She said the APN setting is only for Internet and I need to go to a Chatr shop to check my phone and SIM card. I think I will go this weekend.
I think you bought the phone that has been report as stolen and has been blacklist so it is block on all network in Canada.
QCN FILE
If you are having a problem getting a signal on your I257M message me I will send you the qcn file for it so you can write it to phone via QPST.
