Any SIM doesn't work in this phone, I saw the Customer Reviews said that I need to make the sim card is activated before I installing it, but I just don't know how to fix this problem.

I have a t-mobile sim card from 2006, can i use it on this phone? If not, what sim card should i order? Does it need 2 sim cards to work? If so, do you end up with 2 different phone numbers?

hola si trabaja con sim, lo que tienes que hacer es que veas si las red disponibles para este telefono las tiene la compañia en el que estas, por ejemplo yo uso 850 Mhz

The Samsung Chat unlocked dual sim phone i bought was meant for use in Nigeria,not in the US and it worked good. I think Mr. Richard Whichard's answer settles it all. I'm on T-mobile network and i've not run into any such problem.

IThis phone will not work with the existing sims because it was made for sims which have a large circuit board. T Mobil prior to 2007 had a different SIM card design of teh same dimensions but teh new ones have a smaller circuit board design ( in gold) and thats why they do not work. I think most cell Companies have become smart and to prevent switching develop SIMS that are compatible for their service. I returned mine. A Tmobile technician showed me the reason why it does not work.

This phone is strange. You need to put 2 SIMS in the phone T-Mobile SIMS or SIMPlE Mobile to take the phone out of its stand by mode. If you have an AT&T; SIM you would have to make sure that sim is activated. The t-mobile sims don't have to be activated.

hola, es posible que estés usando un ship movilnet y por esto no te funcione bien a pesar de ser liberado, yo tengo instalado uno digitel y otro movistar, ambos trabajan a la perfeccion, por otro lado debes llevarlo a un centro de servicio para que le configuren lo que se conoce como "apn" y asi poder navegar por internet,

Hello Jennifer, You actually have gotten farther than I did, because when I insert my sim card nothing happens. Sorry I wasn't able to help maybe you can take your phone to your mobile provider. Blessing

Sometimes, when you put a new sim card, you need to turn of the phone and turn it back on. I haven't had any problem with mine but I seldom use it anymore. It was an impulse buy.

We tried our existing SIM card but it didn't work. Then we took it to AT&T; and they couldn't make it work. AT&T; told us we bought a defective phone. I contacted the company I purchased it from and they processed a refund for us. So buyer beware - a used phone may or may not work for any number of reasons. Ideally, the SIM should be transferable as long as the phone and the SIM are issued by the same carrier. Hope that helps.

Hello, The one that I ordered *did* come with a SIM card - I don't know if there is a guarantee that all of them will ship with a card, but I think it probably should. The card is the new "micro" size, I believe, so I couldn't just stick my old one into this phone. However, t-mobile makes it super easy to activate the new SIM (or "update" your SIM information into a new card...same phone number and stuff). Search for "activate tmobile sim" on google, and it's like the third link. Here's the link (hopefully Amazon doesn't remove it) - http://support.t-mobile.com/docs/DOC-4677. Hope that helps :)

sorry about the last reply. I'm on the g4 gsm system. I noticed only one of the sim slots works with my system. hope this info helps.

It might be that you have the wrong sim slot selected in the setup menu. The menu is at the bottom a couple of pages down with a tool theme. The first choice in the menu is the sim slot and you want to pick sim 1. There are actually 3 slots with one for memory so make sure your sim is actually in a sim slot. Hope that helps. Good luck.

People have various experiences with inserting another SIM after activation. Initial activation does not always unlock the phone globally so be careful. Rooting is an option but it voids the warranty.

Looks like unmade an error in setting up the sim card in the device. Try setting up the sim card again using your instruction booklet.

I have not been able to get it to work. I have a sim card that I installed, but I still can't make it work. I would suggest against the purchase.

I am trying to use this device with a full size Sim on gsm network in India. If tried the 3 biggest carriers but always get a 'no Sim found error'.I looked at a YouTube video and I'm definitely inserting the Sim card right.So based on my experience, this phone does not work with gsm carriers.If anyone has any tips or suggestion, they would be greatly appreciated !!

hi if its a sim card then you can just put it in the phone and start using it, because the phone is unlocked but if it doesn't work then i think it will be more advisable to take it to the AT&T; store. but i think it should. hope my answer was helpful.

The one I bought was a replacement for a friend who had one go bad. I switched his sim card over from the one he already had. And it worked fine. I imagine you would have to obtain an activated sim card from your provider if you do not already have one. Sorry that is all I know about it.
