It uses a micro sim

T-Mobile SIM card can not be recognized?

Verizon Note II, yeah, the right place.
Known as a Global GSM phone, it should work with T-Mobile SIM card without any setting, right? At least for Voice.
However, when I inserted the SIM and turn it on, the phone shows "No SIM Card", exactly same as when it has no SIM card inside.
I suspect 1) the SIM card slot broken? or 2) BAD ESN?
Please advise! Thanks!!

[Q] Confirmation that sim slot is working?

Hello all, i just bought one of these phones on ebay. Im not sure if the SIM slot if working. I put an inactive T-moblie and also an old AT&T sim card in there, but the lock screen shows "No SIM card" with a picture of a sim card with a red exclaimation point underneath that it says "no sim card inserted emergency calls only". I wanted to activate it on T-mobile or Straighttalk, but before i buy a new sim with a months plan i'd like to make sure that its working. Does the phone show this message with an inactive sim card inserted? or only when there is NO sim card inserted. Thanks for any help.

I have two amazes. One had a broken SIM slot. The other was normal.
The one with the broken SIM slot showed the no SIM card even when I used my good SIM card.
One of the guys from the forum sent me the phone to tinker with along with the $9 part. I fixed it and now, with an old non active SIM card in it it shows a cell signal. But no data.And when I try to make a call it goes straight to T-Mobile.
It's a very easy fix if you can get the party and the tiny torx driver to remove the screws.
How much did you spend buying the phone?

Get a new SIM first, then a new SIM slot replacement if it doesn't work.

Check with T-Mobile first, you might need to get a new SIM card.
If a new SIM does not fix the issue, just go with Chevy's suggestion and buy a new SIM part from ebay.com. Make sure you use the right tools, and an anti-static wrist strap may help! :good:
If you bought an Amaze at this point in time for over 130$, you probably didn't get the best deal considering how it isn't working right. I really don't understand why people still are buying Amazes when there's much nicer HTC phones lol.

Is a SIM card required

Does the rezound require a SIM card for service, I just bought this phone and it does not have a SIM card, keeps asking me to put it in, I know my old DINK2 had a sim card, and I took it out, I did not have to have it.
This phone will be flashed.

Just got a lumia 920 that's locked to AT&T and displays a sim card error.

I recently purchased a locked 920 that has a sim card issue. I knowingly bought the phone broken since I was getting it for a good price (70$).
Either way, every time you put the phone in, it displays a message stating that the sim card is missing or invalid. Some forums told me to put a piece of tape under the sim card tray before putting in the sim card , but it didn't work unfortunately...
I need help on finding the part to replace my phone. I'll try opening it up later to see if one of the contacts are bent.

Without unlocking the phone it won't accept any unofficial sim card.

I know that. Unfortunately it doesn't prompt me with an option to enter the unlock code when I open the phone with the new sim card inside.

the pins in the sim card slot are likely broken. this is a common issue with this phone if someone used a sim card adapter inside of it.
