If you have ATT or T-Mobile in the US
Cheeseman is correct if you have either of these providers, then you have a GSM phone (I. E. The phone has a SIM card inside it) which under certain circumstances can be used elsewhere.
I have a large collection of unlocked gsm phones (mostly smart phones / PDAs) sitting on my desk and in drawers in my office that I have collected. However, for my local phone (in any of the far flung places I go) I prefer a simple, small phone (I only use text and voice local services) I also do not use one of the phones that I regularly use in the US as my day-to-day phones.
With your local SIM, if you use the phone for 'fun' you may want to familiarize yourself with how to lock the SIM. You may also want to delete the memory and / or perform an occasional factory-reset. If you have a specific local phone (I. E. Something other than your day-to-day phone) it is probably best to store it with the battery and sim card removed (and stored in separate places (harder for someone else to put all the pieces together and will likely extend the life of the battery)
I do prefer to stick with the same brands as my other gear so that I can use multiple phones with the same chargers, USB cables, etc.
First, check the details of your ATT or T-Mobile phone (just google the model number) and see if it is at least a tri-band if not a quad band phone (this refers to the radio frequencies on which the phone will work-I think I previously posted the frequencies for the local carriers-if you have 850MHz it will definitely work in Bs As) Then you need to get the PUC (phone unlock code) from your carrier and unlock your phone before you leave the US! You cannot unlock the phone if you are not within the service provider's network. Your carrier should give you the code without a hassle. I can get mine (for my current phones) directly on the website without assistance. Call customer service, tell them you travel all the time and need the code (they should give it to you)
Alternatively,.
- Go on ebay and buy an unlocked, quad-band phone (unlocked so you don't have to) When you get to Bs As, buy a chip and stick it in (hmmm, sounds like advice for another thread) or.
- Go to one of the major guys and buy the cheapest, no-frills phone with SIM and minutes.
[QUOTE=El Queso]I agree with Facundo about the stolen phones - and screw the punks that steal them! My brother-in-law has had his phone (and cash) stolen twice by little gangs of punks, and I'm sure they went and sold the phones afterwards for a few additional pesos on top of what they stole in cash.[/QUOTE]As for these POSs, I suggest (again) this phone: [url]http://www.defensedevices.com/cellphone-stun-gun.html[/url]

Did you get it directly from a US service provider?

Beezer[/QUOTE]If so, you might be able to get the unlock code from the original provider (although if you are no longer a customer, their incentive to be helpful is lower (e. g. nonexistent) If you still get service from them, it shouldn't be a problem. Also, I am not sure if it is possible to unlock a phone unless you are within reach of the network to which it was originally locked (although, I may be wrong about this)
I have never tried the services that you see advertised online.
My favorite throw-away cell is the Moto v97 us$20-25
This was the high point of the original razr technology--louder vlol, longer batty life and better signal. No camera. Can drop it and it doesn't break.
On ebay, they can be found with patience for under us$25 delivered. I currently have two--I've given away a few over the last few years. A very good simple gsm 4 band gem.
