Lumia 710 Sim help needed

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.

I would check to be sure sim is completely inserted, it should lock into place and need to be pushed in further to eject it.
Similar to the way some micro SD card slots work.

Just restore it to stock JB. Info here: http://forum.xda-developers.com/showthread.php?t=2006946 Look in the FAQ section. Although it might just be a bad sim card. It may be worth just walking into AT&T and asking to switch your number to a new one. If that still doesn't work, then just LGNPST.

It shouldn't be but it could be a sign to internal damage. The door keeps out dust, lint, and other small objects (coins and keys) from breaking the contacts inside. You may be looking at hardware damage.

All that is, is the phone detecting an object being pushed in. It still won't see that "that object" is a sim card until it reboots.

It is probably software related. I was just saying there is a possibility it is hardware related since the sim cover is broken. You won't know until you flash back to stock. Also, does your phone show an IMEI number? Check in settings>about phone>phone identity. Dont post the IMEI, just check to see if there is a number. I ask because my EFS partition got messed up once on another phone and it too wasn't recognising the sim.

Thats normal. The phone will still operate without a sim card. All the network (Edge, GSM, LTE) will still function. This is so that you can still use your phone to make emergency calls. Basically, the problem can only be a few things.
1. Software related (Solution: flash back to stock)
2. Sim Card related (S: get a new sim card)
3. Hardware related (S: repair/replace the phone)
You'll figure it out. Just narrow it down one by one. :good:
Edit: Before you restore stock, why not just try a factory reset. It wouldn't hurt. Backup just in case.
