Can I use any cell phone provider? Or am I limited to Cingular or T-Mobile?

Anything with a SIM card uses GSM while other carriers use CDMA instead. Any unlocked GSM phone can be used with any GSM carrier as long as you have a SIM card (that is active) for that carrier. CDMA phones are built specifically for ONE carrier only, so even if you had CDMA (say Verizon) and wanted to switch to another CDMA carrier (like MetroPCS), you could not use the same phone for each as they do not have that SIM card you can just switch out and replace. Actually, alot of phone manufacturers will "create" certain models that are all mostly the same except for the fact that some might be carrier specific. Example - the Audiovox 8900, could be 8900m for MetroPCS, and 8900v for Verizon, and maybe a general 8900 that is unlocked (GSM) and then might be used for Cingular and T-Mobile by just "locking it" to either carrier (which could be undone) or sold unlocked to anyone for any GSM carrier in the world that uses it's bands -850/900/1800/1900 are the 4 world bands. Some carriers will have more or less features available on their phone model version by what they asked Audiovox to do with it for them.

Not really. You can use it with T-Mobile's pre-paid service or on one of their contract plans. Beware, the phone's software requires access to a service that T-Mobile no longer provides.

As long as the phone is unlocked, you should be able to use it with any operator(who provides GSM service and not CDMA). Is DIGITEL a GSM service provider or CDMA? Make sure the phone is unlocked.

It depends on who's towers Straight Talk uses. You have to do some research, I'm afraid. I go through Ting, personally. If you are a heavy user consider Virgin Mobile.

I never tried to use another carrier but a unlocked phone should be able to use most carriers except Verizon wireless

Yes, if you bought an unlocked version you can use any sim card from any service provider

Yes, as long as your phone uses a sim card you can use any unlocked phone. T-mobile however has a few issues. The T-Zone or myFaves features won't work so if you use those features you probably wouldn't want an unlocked phone.

First of all, can you see your phone provider? You should see like T-mobile or others? If you can see that, please go to your phone provider for inquiry, I think.

No, I'm pretty sure you can only use Great Calls. I don't know which of the major carriers they use.

Unlocked Cell Phones (GSM standard with SIM card) can be used with different GSM compatible carriers worldwide. That means an Unlocked phone can be used with T-Mobile, Cingular, etc. in the USA and any other GSM service provider anywhere in the world. These areOEM Unlocked phones. These phones come directly from the manufacturer and were never assigned to any service provider. These phones usually come in manufacturer's original packaging. OEM phones does not have any service provider's logos or customization. So if your like me and have a pay as you go account, or even if you already have a phone and have a valid SIM chip, then you should have no problems using this phone. Just make sure you save what you want onto your sim before changing phones. Always keep the receipt, know the rules for returns or exhanges and all should be good.

While I cannot guarantee anything, t-mobile and AT&T use the same types of connection, so you should just need the right SIM card.

That probably depends on what your with. Verizon. Tmobile. Sprint. ect. Tmobile is what I have and I can call anywhere in the world free. And its worked better than any other service. And I have the galaxy s3 mini. Hope this helped.

Choose one of Cingular's data plans that fits closest to your usage (all of the plans are fairly pricey). If you only want data service, I know for a fact you can to do so at a Cingular store. It may be possible through Amazon, but I haven't attempted to do so. Beware that Cingular stores currently offer this device for $399.99 w/2 yr agreement, versus Amazon's excellent $199 price.

Yes, you can use for any GSM service(t-mobile, At&t and more) which uses SIM card.
