Hey guys i just was giving a Lumia 710 and was wondering if there was a fix to a problem im having, the phone keeps saying invalid or no sim, but my sim is in the phone, it is a tmobile phone and so is my sim, it even shows my phone number but dosnt connect to my service or anything... any help?
Hi,
Any baseband error will result in this condition. Have you played with custom roms ?
Maybe you have version mismatch wp7/rex, or baseband is corrupted. Maybe
reflash to the latest version and check.
BR
it was like this before i even unlocked it
can you provide links or any help? im a noob when it comes to wp7
Really a strange problem, if you are using a pincode, remove the pincode and see if that helps, otherwise try another simcard.
Succes,

Return the phone, sounds faulty
so ive been searching online and i think the phone is being IMEI blocked by tmobile, is there anyway around this?
Dial ##782# and press the call button now you can see if your phone is having a simlock, if yes search the forum.

Okay thanks, there are not much options left.
But we still have two problems, could it be the phone or the sim-card.
About the phone, did you already a factory reset and installed everything again ?
If not, I suggest to try that first.
Can you also tell me more about the sim-card, did you cut the sim-card yourself to fit in the phone, ordered a new sim, using an old one ?
First, if you ordered a new sim-card, just call T-mobile and asked them if you have to activate your sim.
Second, try to put a piece of paper on the sim-card to make it more stable.
For now I'm out of options,
Good luck,

When I first got the phone both slots worked. I've rooted the phone and installed some things and may have broke something. SIM2 works but the other slot is broken. I'm on tmobile too.
Feiteng GT-A7100 "Mobile Network Not Available"
Oh, gosh, I'm really stuck. Tried two SIM cards (redpocket/att and spot/t) and either works. Sim cards work with
dumber phones. Really like this phone (ie cool android hardware) other than it won't work as a phone.
I also have suspicion about the IMEI. Bought from everbuying.com. please email vjp2 panix com because I dialup and don't
have broadband. But I will try to get back to forum if someone replies. The Phone sees the SIM card (ie, knows name, and some addresses).
I don't know about all those extra setting with initials (some it has, others not).
But it says the SIM card is disconnected. Took it outside, closer to cel towers. Is it possible the sim cards are too cheap.
I only want talk. I've seen doc this phone is 4 bands, others say 2 bands

i have same problem
1) I noticed one of my sim slots (sim 1) was not detecting the sim card. Error message was something like "no sim card" which is different than "no service". In examining the sim slot, one of the gold pins in the slot was not making contact with the sim card. I took a small safety pin and bent the pin slightly up.
** NOTE ** be careful bending this pin up. If you use too much force, you can snap the pin off and then you would be totally screwed.
I then reinserted the sim card and the phone detected it since the pins were now making contact with the sim card.
2) Another thing I noticed is sometimes I get "no service" even though other times I would get 4 bars of signal strength at the same location. I went to settings and disabled the sim card. Waited about 10 seconds and then re-enabled my sim card. It then seemed to reconnect with the phone network.
My carrier is TMobile.

How did you root? can i root my a7100 with armv7 processor device?
please help me i cant even find a way to root the divice
My brother has S3 which was working fine before this.
Today in morning he took out sim from it, the phone was off, and put sim in another phone. The phone was in the drawer the whole time and powered off.
So in evening he inserted sim, turned it on and it shows no sim detected. Did a bit reboots but no good.
I also have S3, so i took my sim and inserted it and it did not detect it.
His sim is working well in my cell phone but his cell phone is not detecting any sim, neither mine nor his.
I have checked for EFS and IMEI problem but both are intact, IMEI is not corrupt.
The phone is not even rooted, and it has 4.1.2 rom and it is the build before the MG4, and he has not even flashed since opening it from box.
Now i have no idea what should be done.
Can someone guide me in this matter?
I would recommend getting it repaired.
Reads as probable sim holder repair / replace

But before that it was working and there was nothing that could have happened to it. I am thinking to flash the latest build but just wanna know before doing something stupid.
I will surely backup EFS, so that i dont lose IMEI.
Hello everyone,
I have Samsung Galaxy S2 international GT-I9100. It fall into water. After that everything working fine excerpt IMEI null/null, Baseband Unknown, No SIM Card Detected. I exhibited it and dryed for a month. When I compiled it up again, same problem.
After that I decided to change the moatherboard. I bought new one, change it, turn phone on and same problem!! After that I install new ROM via Odin. And the problem still exist! How this is possible?? Oh and I want to mention that I can't access service mode. When I try to access it service mode is opened but menu is blank!
What you think the problem is?? Maybe smaller motherboard, because the small one at the bottom of the phone I didn't change. I am very desperate after so many tries so please help me.
Thanks a lot
anyone???

most probably your efs folder is corrupt or some hardware faulty. Do you have any sort of efs backup with you ?
If you have no backup, you're probably boned. Download as many stock roms as you can & start flashing. If that doesn't work, take it to a local mobile repair shop; many have equipment which can re-write the IMEI to the device fairly cheaply.
Thanks for answers, no I didn't make any backup for efs, so today I will start flashing all available ROMs for my country if this will not work I will take it to the service.
Hello Guys, so as described in the title it all started when i wanted to unlock bootloader unofficially, im not a newbie but didn't expect Xiaomi to act like samsung in terms of making it a big headache to unlock the device...
anyway the unofficial method consist of flashing MIUI 7.1.8.0 while i was on 8.0.x.x if im not mistaken
I had my sim in my main phone in the process so im not really sure when did i basically lose the IMEI, baseband, MAC address all these things but i discovered that i lost them and spent like 2 weeks searching and tryingdifferent tutorials (i have like 50 bookmarks and maybe downloaded like 30GB worth of data!!)
Final/Current situation:
IMEI1 and IMEI2 recovered --> can log in to Mi account
MAC address recovered --> can connect to wifi
Service NOT recovered, phone detect the sim, it shows the sim number in settings, even the access points are read from the sim and shown in the Access Point area but whatever i do the sim card shows No service
last thing i did is i flashed MIUI9 beta official, locked bootloader, stock recovery...
I hope this thread get some attention for me and many others as well...ready to answer any extra clarifications
It's Redmi Note 3 Special Edition (SE)
[Product Code is 2015161 which is for kenzo according to thsi http://en.miui.com/thread-449310-1-1.html]
