just got my lg c900 today from ebay, and when i insert my att sim card, it says "invalid sim card"...
But I have been using this sim card on other devices, like nokia 2710 and my touch 3g and they work fine!!
So i tried someone else's sim card(Att), it works too!!!
What should i do.....
You need to unlock the phone to use with other carrier. There are a lot of unlocking services that can help you to unlock it.
Aha!
I had the exact same 'problem' and freakou... er... reaction.
You have to activate a plan on the SIM card. Only then will it stop giving you the INVALID SIM message at startup.

Jesus! Is there no other way out? I didn't buy it from AT&T and don't want to pay for the data plan....
can i just don't make a data plan but just enable the data connection?
If you want to use the phone or Data (excluding Wifi) functions of the phone, you'll need to have some sort of plan or prepaid account associated with the SIM card.
It doesn't mean you have to pay the 'Smartphone' package that AT&T offers (forces) when you get the phone on a contract. You don't even need to have a plan at all! You just need to activate an account online.
Thanks, but actually this is not my contract phone. I bought it from someone else. In my current contract my device is a basic phone, but I enable the data connection function(pay per usage).
But it's still not working...what a wp7....
what do you mean by activating an account online? I already got my account.
Well, on Telus, you just had to activate a phone by entering the SIM number (it's on the little card you received with the SIM or sometimes on the SIM itself) in the 'Activate your Phone' wizard.
Problem fixed!!!!
I call the ATT customer service and they update my sim card information. now it works!!!
Excellent to hear! I'm glad your problem got fixed

i just recived my unlock code from tmobile and i want to test the code and see if it unlocks my phone.
where can i get a foriegn sim card?
is there a website? or can i unlock it without a foreign sim card?
again, i have my code
also, lets say, i am in germany.........
and i get a sim card from over there.........can people still call my US number? or will that change?
is this legit?
http://www.oneroam.com
you dont need a foriegn sim card,
all you need is an "unsupported" sim card... any non Tmobile sim would work
once you have it in the phone and power on you will get a message like
"Please input unlock code"
punch in the code, then it will "find" the network the sim is attached to... so if you use an at&t sim card it will register to the att network in about 30 secs
.....
so mainly is
1. use an unsupported sim card
2. enter unlock code
3. verify it connects to the unsupported network (at&t since those sim;s are easy to get)
4. put your normal simcard back

got ya, thank you for your fast reply, i thought i could do it that way, but just wanted to be sure.
"

the number is tied to the sim
if you put in a sim card from another operator you get a new number
and people can't call the number of your old sim
even if you get a dual-Sim holder and have 2 sim in the device granted it support it
most places the rules apply that if other people call your USA number
while you're outside
they only pay for calling you in USA
and you pay for directing the call from USA to what ever country
you're presently in
if this is fine by you you don't even need to unlock it as tmobile would have
roaming agreement in many countries in the world but at a high cost of cause
Hi all,
I got a HTC Ozone from Verizon. I know this phone supports CDMA/GSM networks. My phone is working on a CDMA network but it also comes a SIM card.
I have the following 2 questions:
If I remove that SIM card the phone still works on the CDMA network.
1. Does anybody know what is that SIM card for?
I have also tried to remove that SIM card and insert a SIM card that I have from AT&T. The phone just says that the card is invalid but it doesn't ask me for any unlocking code.
2. How do I enter the unlocking code on this phone?
Thanks a lot and sorry if this has already been asked but I haven't been able to find anything.

To answer your questions -
(1) The Pre-installed sim card is a VZW sim that allows you to use the phone internationally on GSM networks. You would pay international rates to VZW for that.

I did this and am able to use a t-mobile sim and At&t sim in the phone. You just have to make sure to have the phone in GSM network mode.

hey guys,
I got the unlock code from Verizon (actually my company got it for me because I'm not the owner of the account) However, I don't know how to enter it.
If I insert a different SIM card (e.g. AT&T) it just says that the SIM card is invalid, and it doesn't give me the option to enter the unlock code like with other phones. I also tried to change the network to GSM.
Any ideas how I can do that?
Thanks
ok, I think I found it. Unfortunately they got an invalid code so they have to go through the whole process again
One slight problem for some of us, like me:
I'm about to purchase Ozone off-contract from VZ. VZ rep told me I'd have to put it on an account for 6 months in good standing to even get a consideration to be unlocked.
$350 for this? This is frickin' anti-competitive bull****, I'd be paying full price un-subsidized for the phone, I deserve an unlock.

I found mine already unlocked off eBay for about $290. It was an auction so obviously I can't claim you would pay the same, but it is an option if you don't want to submit to their rules.
as far as how long u have to be under contract... i was told by global support you have to have been a customer to 90 days prior to the unlocking and in good standing.
I upgraded a different line to get the ozone... put it on my primary account that same day and had it unlocked five minutes later. I think u talked to the wrong rep.

Wrong rep? I was at a corporate Verizon store where their Small Business Specialist told me that.
Yep... wrong rep... Global support is different then Small Business Reps.
How many times has one rep told you something that was contradicted by another rep?
I was simply telling you what I was told right before they unlocked my sim.
As a matter of fact, I just bought a BB Tour off eBay that i put on my account and had it unlocked through global support within 5 minutes. Only requirement was I have been a VZW Customer for more than 90 days and I am in good standing.
Shoot, if you want maybe I'll activate your phone for you on my account and unlock it...

My unlocked Tilt broke, and all I can find on Craigslist is an HTC Ozone. My unlocked Tilt is on T-mobile, so I can't call Verizon to get an unlock code
Is there another way to do this?

Same here,
where I work we do not get VZW anywhere in the building. AT&T actually came in and installed repeaters so I plan on getting an AT&T prepaid and put the sim in my phone then I can just switch networks. Is that possible?
I unlocked 2 phones with www.unlock-now.com they work great and fast. I unlocked an HTC Imagio and an HTC Ozone.
go the unlock code from htcunlockcode.info and following instructions came along the code.
1. Switch to GSM mode
2. Go to Personal
3. Go to Security
4. It will says "Please enter the sim unlock code to disable the SIM lock"
5. Enter unlock code.
6. Reboot.
Worked fo me! hope the instructions will be helpful, as I see lot of people asking this in different forums.
xoxoxo
Jane.
thanks very much！
find the option to enter unlock code finally！
I got a code here http://unlockcellphonecode.com/code-for-unlocking-htc-mobile-cell-phone and they sent me the code and instructions ..
using iwireless sim card in it now..
I have a MyTouch 3G w/3.5mm headphone jack that I bought from Craigslist. I just use T-Mobile ToGo Prepaid, so I had to get the phone unlocked (got unlock code through T-Mobile for free) and I used my mom's AT&T SIM Card to activate the phone.
After doing that with stock firmware, my T-Mobile SIM card still won't work in the phone. I got zero bars and with a small "X". I thought maybe T-Mobile purposely blocked non data plan SIM cards in their stock ROM, so I rooted and installed Cyanogenmod 6 RC2. Everything went fine with the rooting and upgrade, but I'm still having the same problem with my T-Mobile SIM. It always says "No Service". If I try to dial a number, I get "Mobile network not available." In Settings->Mobile network settings->Network Operators, it shows both AT&T and T-Mobile as available networks. If I touch T-Mobile, I get "Unable to connect to this network at this time. Please try again later". The strange thing, is everything works fine with an AT&T SIM card! I'm at a loss to figure this out. Are these symptoms of a blacklisted IMEI? Or do these symptoms indicate something else?
UPDATE: Talked to T-Mobile chat, IMEI is NOT blocked which is good, but it's still not working.
had the same issue...I used my friend's AT&T sim with data plan to sign-in to google. I had to enter AT&T APN settings and choose AT&T network in the menu.
Everything went well and I put my prepaid togo sim card. Got no service message and no bars. I went then to menu-settings-wireless controls-mobile neworks-network operators. It scanned networks for a minute and found t-mobile which I chose. Right after that it connected to network and I was able to make my first call from prepaid card
Unfortunately, that doesn't work on mine. When I touch T-Mobile, I get "Unable to connect to this network at this time. Please try again later."

are you sure your t-mobile sim card still work fine? i did research quite a bit this issue yesterday and many people confirmed that prepaid card works fine for them. check your network settings again and reset them to default
Yeah, it's the SIM card I use in my iPhone daily. My wife's SIM doesn't work in it either. I've reset everything to defaults, wiped everything, and even installed Cynanogenmod with no luck.

sorry to hear that...maybe you should try to call t-mobile or visit a store
I did talk to T-Mobile, but they only suggested a full wipe (hard reset) which didn't work. I guess it's probably broken, and since I bought it second-hand, not covered under warranty. It's unlocked so I guess I could try to recoup my losses by selling it to someone w/AT&T.
Going to Cancun on Thursday. So I called Spring about my GS4 & GS3. They enabled the codes so that they connect to the towers in Mexico. But you still get charged $2.99 per call and for each text message. But I thought i read you could put a Sim-Card in these phones for them to work international. Anyone ever tried this?

Ok, you need to do a little more research on the phones themselves. The GS3 does not have a removable SIM, it is embedded, so there's no chance of you inserting a local SIM etc.
The GS4 does have an accessible SIM slot but it is locked to Sprint. Even if you insert a non-Sprint SIM it won't work. Sprint want's you to pay their rates for international GSM roaming.
Even if you meet their requirements and get Sprint to unlock your GS4 SIM slot, it will work for calls and SMS with a non-Sprint SIM but no data (apparently some have found out, look in the forums)..

I haven't been out of the country yet to verify it, but I believe if you're rooted you will be able to get data by making a build.prop edit so you can add the appropriate APNs. Some people have reported though that they didn't need to do this, and data just worked automatically when they put in the SIM. I believe it was a UK carrier's SIM that just worked. I'll have a chance next week to try it out in Costa Rica and see if I can get data working.

Hmmm. Lots of conflicting info on this. Someone did the build.prop thing and mentioned that the apn options were grayed out, so he basically couldn't edit anything. Even posted screenshots. Please try out your scenario and keep us informed. Thanks.
I have tried every code mentioned, in here, that was successful for others but not for me.
I started by buying my Galaxy S4, out right, at Walmart for use on Family Mobile. Poor signal everywhere except in my house. The phone has T-Mobile support as far as towers go. After about three weeks I had my phone number transferred to Straight Talk and they sent a SIM card for use with AT&T support. The phone was purchased as an unlocked phone, I did all the codes in this forum to check and sure enough, it is supposed to be unlocked, BUT, every SIM card I get from Straight Talk gives me "INVALID SIM CARD" when I boot up the phone then a black screen comes on with a subdued color message saying, "Sim network unlock PIN" and all the help from Family Mobile, T-Mobile, Straight Talk, Walmart and AT&T, have not helped my situation. I can't write a new APN and store it because I have an invalid SIM card. I have tried the service mode and did everything mention in these forums but no luck so far.
I really like the device(my NOT-Phone) but it does not function as a phone. Can anyone help with this one?

No warranty in Walmart?!
If it connects to T-Mobile towers out of the box, can you borrow a T-Mobile SIM from soneone and go through the SIM unlock procedure? I'd do that just to make sure it's SIM unlocked. Then try Straight Talk with whatever APNs they use. Do this on stock and once you can confirm you get that far and it's working then go crazy. Good luck.

If I put the original, 1st SIM (Family Mobile) that I bought, back in, I do not get the Unlock Sim code message but I also do not have service because I already had the number ported. I've been that route. I tried the APN routine but it won't save because I don't have service with that SIM card. I go into the unlock routine through the service mode and it says it's already unlocked. Any Sim card from Straight Talk gives me Invalid SIM.
I'm going to return it to Walmart and try another phone.
