Thats because the t-mobile sim cards aren't designed to be used in at&t phones. you either have to buy a new t mobile phone or get a plan with at&t.

Code for unlock sim card of 8525 att pc phone


I don't think anyone here can give you a sim unlock code. Unless you want to pay for it you can buy from ebay.

Here's the free solution.

Run this unlocker on your phone. Follow the instructions exactly. Don't unlock the CID unless you planning on installing another custom rom other than ATT on it.

I assume you mean the phone is asking for a network code or password before the Start Menu is available, ie, phone can be used.

If this is so and it is asking for a network code, then you need a SIM card that matches the carrier the phone was designed for. If it is ATT/Cingular, you can buy a SIM card from the new ATT/Cingular network for $6. It is a pay-as-you-GO phone SIM, but once you have it, you can call ATT to as for a number xfer as well as a standard monthly contract using this SIM.

If it is from the old Blue ATT network, then it cannot be used on ANY carrier unless it is unlocked for use on ALL carriers. This would be noted witht the docs that came with the camera. If nothing says ATT/Cingular, and especially if someithing says ATT without Cingular, then it is probably an old Blue ATT phone. You can buy a BLUE SIM off ebay which will get you to the point of being able to use the phones functions, but it will not work to make calls until you unlock it and replace the BLUE SIM with another current carriers SIM. Sprint will not work either because it is not a GSM ATT type network. Cingular and T-Mobile yes.

Google phones model number and UNLOCK and you will find a way to do it yourself at no charge if you have an XP or earlier PC with a USB port. Vista OS cannot be used to do it with the downloaded unlock software. It is also very hard to find anyone that can do it selling Unlock Codes based on phones IEMI code.

If it is not a network lock message, then it may be the last users personal lock password. In this case, you can hard reset the phone by holding down both right and left softkeys while powering on the phone.

Unlock my blackberry 7290


Like you being with T-mobile, I bought a cingular phone off ebay that wasn't unlock. My sims didn't work either. My network just said call Cingular which is now AT&T and they gave me the MEP code to unlock it. Beware, you need to confirm all of your information from your network before they will help you.

T mobile wing unlock code


Call your cell phone carriers customer service and they may email you the unlock code and instruction for free within 24-48 hours. Tmobile did this for me several times on different phones. Tmobile will send you the unlock code and instructions via email for free for their customers within 24-48 hrs. But you have to call their customer service (US) 800-937-8997. I tried emailing them initially but no response. When I called they were so accomodating and didnt even ask why I wanted the phone unlocked.
Once they send you the code its simply inputting the code they provide. However to do this you must first put in a non tmoile sim. As far as I know this is only cingular or a foreign pay as you go sim card. Luckily I had a foreign sim that I saved on a prior trip as I have other unlocked phones and this worked for me. None of my friends had cingular so I could not use their Sim to do the unlock code on my phone. Nextel, Sprint and I think Verizon also dont use sim cards.
Alot of cell phone stores and kiosks will also unlock any cell phone for you for about $30.00. You may have to leave the phone with them and pick it up later like an hour or two later if they are busy.

Get an ATT/Cingular network SIM card for $6. It is a pay-as-you-GO phone SIM, but you can have ATT xfer your number to it and also make order a standard monthly contract plan for it.

If it is really an older ATT nework BLUE phone, then the new ATT Cingular network does not support it. It must be network unlocked to use on ANY carrier.

You can google the phone model and UNLOCK to get free unlock software you can use yourself on an XP PC . Software won;t run on VISTA.
