Yes, you can.
Your provider can't dis-allow you to use a phone.
I currently have a Nokia 6340i with Cingular. I am thinking of upgrading to a Motorola V400. My question is can I swap the sim card back and forth between the phones? The reason for asking is that I have a hands free car kit for the Nokia and I really hate the idea of losing that while I drive.
Is this something that Cingular allows?
Yes, you can.
Your provider can't dis-allow you to use a phone.
Thanks. I just had my rep order the phone based on your reply.
You will experiance a problem. Bjorn is correct that Cingular cant disallow you to use a phone..
But the Nokia 6340i and the V400 are two diffrent technologys. 6340 being GAIT and v400 being GSM. Granted they both use SIM cards, but Cingular sets up these two types of phones in their billing system diffrently.
I can almost guarentee you that you will expeiance a few problems ( ie. Roaming charges and such) due to the Technological incompatibilitys
FWIW in case it matters, I am currently on a nationwide (no roaming) plan with my current GAIT phone.
Should that make a difference?
Well....I think both of the replies are correct but at the same time, the SIM and the IMEI in Cingular's billing system will be associated. Therefore if you attempt to put the SIM into your nokia 6340i from your V400...it will bill you according to what you have as your pricing plan. The GSM technology registered in Cingular's Billing won't change b/c the IMEI will still be registered as GSM. Know you will not receive the benefits of GSM but it should work...Try it a few times the first month and check your bill....
I currently have a Samsung s307 and a Nokia 6340i. I use the small S307 in cities and when I travel to rural areas I put my SIM in the 6340i. It works for me.
Here's a similar ??. I was with AT&T and on they're TDMA system when i opted to get a new phone. They really didn't have anything that i liked on the GSM network (originally i wanted the nokia6560), i ended up just going with something that the sales rep suggested that i thought sounded good, the Siemans M56 (the little orange one). Well, i hated it and took it back like four days later, but i kept the SIM card. Now i have the v400 with Cingular and love it but was curious if i could swap out my cingular SIM for my AT&T SIM without any problems. I also heard that the Cingular SIM locks alot of features on the v400 that other SIM cards can unlock. Anyone know anything about this??
I'm not sure about Cingular locking out some features (I'm curious about this, too, now - hopefully someone will post), but the AT&T sim card will work perfectly in the V400. I have Cingular and my boyfriend as AT&T Wireless w/ a T68i, and I did an experiment and his card worked fine in my V400 - it displayed his contacts and "AT&T Wireless" instead of Cingular on the main screen.
Yes you can swap sim cards. However the sim card is not what makes your phone work with cingular. Its the codes listed under the battery of your phone. Your sim card simply acts as memory, containing phone numbers and ect. To be able to switch phones on you account, the Cingular database would need both sets of codes from the two phones. For this to happen you would need family plan that would support the two phones. So unless you have familytalk plan it wont work.
:?: Am I missing something? I thought the original post was about switching the SIM card from GAIT to GSM, not the other way around.
Since the account is set up as a GAIT plan, and when the card is in the GSM phone it can not roam on analog only use GSM, how could there be any roaming problems?
I have two numbers on the Nationwide GAIT family plan and will use one of the SIM cards in a 6340i and the other, while in the Cingular files as a 6340i will be used in a 3595.
WRONG WRONG SO WRONG U DONT NOW WHAT YOUR TALKING ABOUT i switch phones all the time with out a prob and so do so many others out there
I have a friend who recently dropped his phone in the water it is a Sony ericcson T237 (cingular). For awhile the hour glass would only come up when you turn it on but now it just says insert sim card. So I assume the one he had is gone(dead) and I am bidding on a new cingular sim card on eBay. I was wondering if this card would be compatible with this phone or if there is a difference for cingular phones. My friend gave me his phone and I would love to transfer my plan to it.
He also switched phones after he gave it to me but his sim card would still funtion right?
Can anyone give input? Greatly Appreciated. Thanks!
To your first question. You should have a problem using the SIM card off ebay... as long as it hasnt been used before and it is compatible. Some SIM cards are market specific... so you might be running a risk of getting an imcompatible one, i usually recomend going to a cingular store.. you can usually get one for less than 25 bucks...
Second question: his sim card would not work with your account.. once a SIM is used for a particlur number it cannot be reused.... you would have to get a new one
I have an easy question. I have a v400 that has been malfunctioning. Can I buy a v400 of ebay and just use my sim or do I need to contact cingular to have it activated? Can this sim be transferred to a different motorola model and still be used?
yes, you can use your sim in any cingular branded or unlocked phone.
I have a question, I am a private investigator and I am wondering why would a person swap SIM Card between multiple handsets and if the person was a "bad guy" what benefit would this action have.[/b][/u][/i]
The only thing I can think of is that the different phones have different contacts in them.
I do know that AT+T can tell what phone/model you are using based on what phone has the sim card in it.
Yes we can see every serial number and what kind of phone that the sim card is used in. Also if they switch sim cards we can see that too. So not sure why anyone would think they can hide anything.
Thank you for your input
other than to use a different device.nothing. the phone number is the simcard.
thanks elmo 01
I just bought a blackberry storm fully unlocked and need to swap the sim cards. I am currently using a Motorloa w385 with no data plan on an ACS network. They do not offer the storm but I know it works on their network since my GF has a storm through Verizon that works fine up here in Alaska on the ACS network. I know the data portion will not work until I sign up for a data plan but my question is.
- Will I be able to recieve and make calls if I just swap out the sim card?
I don't want to change my phone number and I still have about 8 months left on my current plan. Any help would be appreciated (including links where I can find out more information). I'd also like to know where the sim card is located on the w385. I think I have to remove the 4 torx screws in order to get at it but I don't want to disable my phone until I know I will be able to use my new one for phone calls and IMs.
I currently have a [b]CU720 LG Shine[/b] and my friend is giving me his [b]Quickfire[/b].
I tried switching the SIM card between these two phones back and forth few times to see whether I wanted to keep the Quickfire to use.
At first it was working fine just fine. After a couple times of swapping phones repeatedly, it started having [u]problems sending text messages and making calls[/u]. It wouldn't let me send but it recieved the calls & text messages just fine. This problem happend regardless to which phone my SIM card was in.
Later I took it to the AT&T store and they said the number for the Message Center was changed and they changed it back. I stuck with the original LG Shine since then, but I would like to switch it back to Quickfire because my current phone's battery is slowly starting to die faster. (In addition the camera/camcorder is not working)
However, I don't exactly know how to personally fix this problem without having to go to the AT&T Store again. (Also not sure if they can do that for the Quickfire)
Does anyone know how to fix this problem at home? Or should I take it back to the AT&T Store?
And am I allowed to switch between phones to a friend's old phone?
