my phone thinks it's roaming - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hello everyone, been using the helpful tips on this forum for a while, but it is my first time posting here.
I am in China at the moment, so I had to get my phone unlocked.
I purchased an unlock code, and was able to have my phone working with other sim cards.
My problem is, when I have the Chinese sim card inserted, my phone still thinks it's roaming.
I have tried messing around with the network settings, but have not been able to get anywhere.
Is there anyone here who can help me with this? Thanks so much!

Phone Not Allowed MM#6

Hi,
I recently unlocked a Vario III. It was successful in the sense I could insert a new SIM card without it barring me from starting the phone, I do end up getting an error when inserting the new SIM, "Phone Not Allowed MM#6". Does anyone know what that means? I inserted a T-Mobile SIM and while it doesn't give me the error, it doesn't connect to the T-Mobile network either.
I'm mostly curious to know if this is a defect in the phone, network, or the unlocking procedure.
Any help would be appreciated. Thank you.

Wow........digging in the graveyard.
Have you check with your carrier to make sure that the sim you are trying to use is enabled for the network and not locked . The sim unlocker, unlocks your phone to use any sim. It does not unlock a locked sim card.
Have you ran the sim unlocker?

I'm in Bolivia. I have a samsung galaxy s, I unlocked with SUperOneClick (for rooting) and sgs tool to unlock it. Then after using a local carrier for about two weeks my phone got the mm#6 error. I was looking for solutions, and then my brother realized that I have to register the phone with the line (IMEI with line). Here in Bolivia exists a law that block phones if they are not registered at someones name and Id. So with nothing to lose, I called assitance of the carrier and register the IMEI I found in the Android menu (About phone>status>IMEI) with the GSM chip/line I have. Wait for 20 minutes and voilá! phone got signal and it's working now. I hope still working from now and on. SO IF YOU HAVE THIS TROUBLE CALL YOUR CARRIER AND REGISTER YOUR PHONE'S IMEI WITH THE LINE YOU ARE USING, IT'S SIMPLE. YOU CAN TRY THAT BEFORE GETTING INTO SOFTWARE STUFF.
HOPE THIS HELP SOMEBODY.
GOOD LUCK!

[Q] Help Needed

I have recently purchase a Note 4 clone phone from China. It works very well but I have a problem. When I got it I inserted an EE micro simcard which work fine whilst I waited for my proper talktalk simcard to arrive. Now however when I insert the talktalk simcard in I get no signal and the message emergency calls only.
I think with these types of the devices, once you insert the first sim card into it, they tend to lock onto that network and won't work with anyone other.
My question is therefore:-
Is there a way to unlock a Note 4 clone phone
If the phone can not be unlocked, I was thinking that if I back up the ROM and reflash the phone with the same ROM it might fix the problem. But I do not know how to back up the ROM. I've read a number of threads but still remain confused.
Any help would be greatly appreciated as I can not use the phone at all now. The device is rooted.
Thanks in advance
Any help guys

[Completed] Sim Card Error

Hi ,
I recently bought Vodafone Smart Ultra 6, which is obviously locked to Vodafone. I did all the start-up settings and everything was running fine. Since my actual network carrier was EE ( Orange ) I unlocked the phone, which worked alright up until the point where it suddenly the phone would lose reception and regain it at random times. I thought that since my sim was really old and cut with a template to fit the nano sim requirement, I messed something up. I didn't mind swapping carriers since I wasn't that happy with my tarrif, so I ordered GiffGaff sim, got my PAC number from EE and activated my new GiffGaff sim with my old number.
I know for a fact that the sim works, because I tried it on different device, but my phone acts like it's locked to EE after the unlocking I did from vodafone. Every sim card I insert is unrecognisable by the phone, except the old EE card which is no longer active.
I tried doing factory restore, which didn't do anything.
Dialing *#*#4636#*#* and turning the radio on and off -> still nothing
I have no other idea what to do and I can't find any solution on the internet.
My android is 5.1.1 which I read that has similar problems on different devices, but none of the solutions I found worked for me.
Any help will be much appreciated.
I am sorry if the post is confusing and doesn't make much sense :/
To summarise:
The phone was locked to Vodafone and Unlocked immediately with an EE card inside
Now the phone constantly shows NO SIM CARD - Emergency Calls Only ( tried on GiffGaff and Vodafone Sim )
No Network Connection - Can't connect ( tried on EE Orange after initially unlocking, the sim is no longer active)
Thanks in advance!

[Completed] Huawei p9 no calls or text messages

I recently bought a secondhand phone from someone. It was locked to a certain network so I tried to get an unlock code from two different websites and they both said they couldn't find the code for that IMEI.
I bought a sim card from the network it is locked to and it registers and shows it has signal but I can't make calls or send texts, but strangely enough the very odd time it starts working normally for a few minutes and then stops working again. Since I got the new sim card there has been no problems with the mobile data 3g and 4g.
I brought it into the networks store thinking it was a problem with them but they tried other sim cards and it still didn't work.
Does anyone have any suggestions?

It could be a stolen phone with fake IMEI but you could try flashing a different firmware for your device to see if that fixes the issue. The experts here

G981U Unlocked no service after update

Hi all, new noob member here with hopefully a simple question. I bought an unlocked S20 with tmobile firmware about a month ago. I'm using a verizon SIM card and everything worked fine until yesterday when Tmobile sent out an update. At first I had no mobile data but could still send texts. After searching, i saw under my SIM card status it said IMS not registered. Not knowing much about this stuff I was thinking that maybe I needed to flash verizon firmware onto my phone and that would fix it ( I have not done that yet). I went to the verizon store and got a new sim... same issue. I also found a website listing access point details, I plugged in all the information and now I have 4G but i am still unable to send texts. I'm wondering if anyone has any ideas as to what my problem might be. I'm trying to avoid flashing new firmware onto my phone because I don't have a great understanding of how to do it, and i really dont want to brick my phone. Any suggestions would be appreciated.
