At the moment my 3g sim does not work with my qtek2020i.
I am wondering if there is a crack or update or something as i have used the xda unlock tool and it still says missing or invalid sim...it works fine with the vodafone and virgin sim i have spare..any thoughts would be great.

I had bought a AT&T Tilt off ebay and in the States it works with my Cingular network. However when I travel as I am now in Greece and use the Cosmote SIM card it states that the SIM is not inserted and thus I am stuck. Cosmote runs on the 900/1800 network and Cingular runs on the 850/1900. The TyTn II is supposed to work on each and every frequency. It was supposed to be unlocked when I bought it but I don't know exactly what to do now.
Anyone help?
The Card is not even recognized, this points more to a broken SIM Card. The TyTn Can operate in all these Frequenzies and would prompt an error that this device is locked to another network if it wasn't unlocked. So this error message is more like there is no SIM Card inserted.
Have you tried it in another phone? cleaned the metallic contacts of the Chip?
Maybe you can try the unlocker program, to make shore it really is unlocked.

Try to check on Phone settings if Network selection, Type and Band are in automatic mode.

The Cosmote SIM I have for my TyTn works great in my friends K1 Motorola KRZR and his brother's RAZR...Both of which were unlocked in the US and also have greek SIM cards.
Does there need to be a special 3G SIM card inserted for the device to operate?

Its telling me I have to pay to check if its unlocked....I don't want to shell out $40 for something that "might" be done already
My v1615 (with Vodafone) showed the same error after owning the phone for 2hrs! Vodafone confirmed the device had a hardware fault and issued a replacement straight away - new handset has been fine.
I'm not saying that's the case with yours but it's already highlighted to me that the stability of these phones can be flaky at times (having been warned by several people before buying)
Hello.
I have an Atrix HD from ATT, I bought it unlocked at Ebay. I used it with my ATT sim Card, then with Movistar in Colombia for vacations and everything was working great. Then I came back to the US, used a T-Mobile sim card and now I can not use any other sim card. The only one it accepts is the T-Mobile one and it works fine. If I pop any other sim card it gives me no signal (a white cross appears in a red circle where the circle bars should be).
My phone is rooted but I have not flashed any ROM or done anything else beyond installing Superuser and Titanium Backup. I already did an internal and an external reset and none works: The only sim card that gets signal is the T-Mobile one. Called T-Mobile and they said they cant help me since the phone is not supported.
My hint is that somehow the T-Mobile sim card switched my frequency bands. Whats funny though is that now I am in Colombia and when I insert the T-Mobile sim card and check which network is my phone connected to it shows Movistar and the signal bars are great. If I pop up my Movistar sim card it gets no signal at all.
Any help will be greatly appreaciated.
You must have setup the sim card lock disable that and then try putting in another sim

Is the phone sim unlocked? I don't know how it works with Sprint but that would be the case with GSM providers
If it's Sprint, it's CDMA.AT&T and T-Mobile are the only GSM providers in the US. However, it should work there if you get the SIM unlocked. The SIM unlock code is formulated based on the IMEI, so there are three ways to get it:
From Sprint. Probably the simplest, but tricky if you're not the phone's original owner.
Pay a site or unlocking service with the algorithm that decodes it from the IMEI. Usually runs around $10-$20.
Try the steps in this thread:

You can also try this app, but it only works on rooted phones running the original ROM:

Bro, A CDMA PHONE CANNOT BE UNLOCKED. IT WON'T EVEN WORK ON ANOTHER CDMA CARRIER LIKE VERIZON. ONLY SPRINT SIMs WILL WORK.
Make sure u buy a GSM phone if u plan 2 use it on another carrier.
But the phone uses GSM! It picks up the network here but I just cant get the unlock box

Then it simply isn't a Sprint handset. CDMA phones can only work on that particular network. The phone is custom-made just for that network
How do I use my AT&T sim because I inserted it and Cyanogenmod said RESTART TO USE MOBILE DATA OR WHATEVER.
Restart and nothing...
HTC Sent me my IMEI unlock codes and I just wanna get this working already....
I just need to use the 1900Mhz band for 3G.... It's a supported band for GSM 3G ....
THANKS
Yeah? I am S-OFF finally I thought that may help...
Basically the "Network Operators" screen is greyed out can't register with ATT
Anyway which specific rom should I use?
Why can't I unlock it for all ROM's? I want to use Cyanogenmod because of it's awesome battery life and light-ness....
Anyway is there a different way the sim goes in the slot than AT&T? I got a message it says SIM Not Detected.
I'll look it up...
THANKS
Still nothing to this day cannot get it to work on AT&T can someone help?
Phone works fine with a particular network (Vodafone). When I insert a sim card from a different network, there is no reception and it says emergency calls only. However, it does not ask for an unlock code so I don't know if the phone is actually locked and how to input the network unlock code.
I purchased my Mate 20 X 5G from Vodafone UK and it works with other network SIMs. Vodafone don't lock their phones to their network.

My P30 Pro was initially working with my Three sim. Then, after a couple of months, it randomly stopped working and said emergency calls only at the top of the screen. I tried the Three sim in another phone and it was working fine but wouldn't work in my P30 Pro. Only Vodafone sims now work in it. However, I'm not entirely sure it's blocked to other networks because when I insert my three SIM, it doesn't prompt me for a network unlock code.
