Can One SIM Card be moved between 2 phones?

Juan Pablo

I am presently using a CDMA cell service provider , hence I
am not familiar with GSM phones and SIM cards.

QUESTIONS:
If I have an activated Cingular service account , two GSM
Cingular phones, and ONE SIM card, is it possible to use
either phone merely by swapping that ONE SIM card between
them?

Would I have to contact Cingular to remotely switch their
service from one phone to the other as well as swapping that
ONE SIM card between them?

Must both Cingular logo-ed phones also first be unlocked to
do this SIM card swapping between them?

Thank you for any comments. ---Juan

Yes you can do that.

Providing both phones are either A.) locked to Cingular GSM or B.)
Unlocked GSM you can do that. I have a spare GSM phone laying around. I
once had to take my previous phone in for service and just poped up the
SIM and put it back in my old phone. Since I stored most of my contacts
on the SIM they came over with the SIM.

Yup. I do it all the time.

Nope--no need to call the carrier.

I have all my phones from Cingular and can freely move my SIM among
them and it just works.

Like the others, I've been doing it for a while, until I settled on a new
phone that could do what both the old ones did.

Keep in mind, though, that while these SIM cards are surprisingly durable,
they are not meant to be passed around like a joint at a frat party.
Eventually you'll create gouges in the contacts, and they will fail, ruining
the SIM. Not a big deal, as long as you keep your contacts backed up.
Cingular should be able to replace it quickly.

I've heard you can clone SIM cards. This would be a better idea in the long
run, if you can remember not to have both phones on at the same time. In
fact, it would probably be a better idea just to have a spare programmed SIM
handy, just in case.

Cloning would be the perfect solution for me as I switch back and forth
between my Treo and MPX220. Taking out the sim and swapping it is not a
major pain in the XXX, but maybe a minor one. Having a cloned card in one of
them would be convenient and I could just power up the phone I want to take
with me. I know it's done for illegal reasons, but that's not my intent
here. Anyone got a source for getting this done?

A quick Google search brought up several sellers that offer cloning gadgets.
I'd try Ebay as well.

Cloning a SIM card isn't just something done in a dark room by high tech
mobsters. There are plenty of folks in the same boat as you, who need two
phones but don't want to pay for an extra cell phone line.

But then there are folks like me, who'd never remember to turn on only one
phone at a time. That's why I had to settle on just one phone.

Curious, how do you like your 220? I'd love one of these, but I've heard
too many bad things about them, along with my own poor experiences with
Motorola phones.

Interesting that you should ask that question. I have two 220s, one of
which has performed flawlessly for almost two years, while the other
went"dead" and had to be replaced before the end of the first year. The
replacement lost sound and had to have a cable replaced inside (at least
that's what the Motorola repair man said -($60)then later refused to
cooperate when attempting to move photos to my computer with MPT. Now
works intermittently. Have mixed emotions about Motorola!

Thanks for the info.

My wife's V400 had the same issue, and apparently so have many of Motorola's
phones. This is actually an improvement. I went through two Startacs, and
they wouldn't even get a solid signal for more than a couple minutes.

I avoid Motorola like taxes after all that, so I never even gave the 220 a
chance. Now I'm glad I didn't.
