My TyTn II doesnt recognize my SIM card

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)

Galaxy-s not working 3g or gprs

Hello,
in Uk a brought a Galaxy-S (T-mobile) and unlocked it. Now I'm back in Italy and I put my old SIM card. The Phone works, except for 3g, edge or any mobile connectivity. I think there is two options:
- The phone is still locked.
- My sim is very old (from 1999), may be no more compatible with 3g.
How do I find out which is the case and how I solve that?
Thanks guys (girls too).

No network
Hi m8
Could you please check your imei number, I did exactly the same.
I bought my sgs on firmware 2.1 & unlocked it via free unlock tool, I then messed with some new firmwares. Recently tried to sell my phone as unlocked but when buyer put their sim in, It shows a signal but no data network connection.
After messing around with different sims i did a check & noticed my firmware is some stupid 04999????
Regards
Mark

What does that mean?? Is it related to IMEI somehow?? What should I check about it? How do I fix that? I've 2.2 by the way

[Q] AT&T SIM card issue

I have unlocked my Z1s from T-Mobile's network so it should work on AT&T as they are both GSM and use most of the same bands. After unlocking it and verifying that my phone is indeed unlocked I put my AT&T SIM card in and the phone reset but it does not recognize the SIM card. Is this something AT&T needs to solve, or is there a way I can remedy this issue?

What method did you use to unlock?

I purchased an unlock code. I entered it and it shows it as being unlocked.

Seems like your phone/imei is blacklisted...query the national blacklist with your imei to get it confirmed

The phone was on T-Mobile's "blacklist", it has since been removed and says that it is ready to be used. The phone still does not read the AT&T SIM card. I am wondering now if the SIM card is locked, or if it is a hardware issue. Thoughts?

U.S. Galaxy Note 4 on Wind Mobile in Canada: Can't Connect to Network

1) My friend (U.S.) gave me (Canada) a T-Mobile Galaxy Note 4. I am trying to use it with Wind Mobile.
2) He claims that T-Mobile performed a carrier unlock, which seems to be confirmed because putting a foreign SIM card in does not ask for an unlock code.
3) My Wind Mobile SIM can't register on network. I tried a Rogers SIM as well and a different Wind Mobile SIM and they didn't work either.
4) The Wind Access Point Names have been entered, but manually selecting the network does not work either. It just says "Unable to connect, try later".
Am I missing something here? Is there another type of lock I need T-Mobile to remove? Do I need to flash the ROM? Thanks in advance.

If same sim cards work in other phones i would think that phone is blacklisted. On the other hand nowadays tmobile can issue temporary unlock codes for international travel. I dont know if Canada is considered international or not. Tmobile will permanently fully unlock device when paid off.

VERY Odd Problem - SIM Card Locked, Requesting PIN. Only on This Phone & SIM Combo

VERY Odd Problem - SIM Card Locked, Requesting PIN. Only on This Phone & SIM Combo
On each boot, the phone asks for "SIM network unlock PIN", and otherwise will read "No SIM card" in the notification bar.
What's odd however is this phone is unlocked. It's an AT&T Nexus 6, and was previously working under Cricket Wireless. The SIM card is from Mint Mobile, and works with my unlocked LG G5. It's only this phone & SIM combination together that's causing issues.
Trying to access APN settings gives the message "Access Point Name settings are not available for this user".
I've tried factory resets, as well as full flashes back to stock, etc.
I've never encountered this before, if anyone has any ideas or input I'd appreciate it.

Sounds like it is NOT unlocked. Since Cricket Wireless is an MVNO directly owned by AT&T, it makes sense to me that an locked AT&T device may work on Cricket.
Test with a friends SIM card. The Nexus 6 works on all carriers in the United States- Sprint, Verizon, Tmobile or AT&T. If their SIM card does the same thing, yea this confirms that it's locked. Buy an unlock code, it should only be a few dollars I reckon.
edit: also please note there is a difference between an unlocked/locked bootloader and unlocked/locked network. They are NOT mutually exclusive.
