It means you can put a sim card from whichever company you want. You are not obligated to stay with one company for phone services.

That means it can be used on other carries not locked to just one like AT&T;(which I use). Though be warned if you need GPS for travel, mine couldn't pinpoint so it was a pain to try and figure out where I was, also there is a lot of bloatware(programs you can't remove easily) that really limited the space I had available until I put in a SD card for extra storage. Honestly it's a nice gaming device with a passable phone side but other than thought I feel there is better options out there. If my GPS worked I would recommend it whole heartily but sadly I can't.

That means that the phone is a smart phone and will require you to have data services with your provider. Your provider can provide more information and pricing. Thanks, Tonya, Taylor Wireless LLC

Yes, no problem because it is unblocked. However, check with your phone company if they carry this phone.

I don't know, but I doubt it. You should ask Uniden about that, however I don't recommend this phone at all.

I am sorry I do not know, but from my experience with Uniden phones I would advise you to avoid any of them No customer service, very shoddy products, terrible quality.

It is a phone that can be used directly from any operator in your country. Just plug in the ship and use it.

I don't know - we have only had it a couple of months and have never looked into that feature. But we really like the phone - easy to use and easy voice mail. Maybe you could call their tech support to find out.

"unlocked" means it should work anywhere the standard is supported. The US and Japan are two places that have a lot of carriers who don't support the standard. The rest of the world generally it's going to work. There are slight differences in the data standards in different parts of the world as well as the GSM bands--900 and 1800 in most of the world, 850 and 1900 in the US (and apparently Panama per another answer.) Many smartphones are "quad band," meaning they include all four of these.

Locked means it is for a specific carrier such as Verizon or AT&T.; Unlocked can be used for any carrier that uses sim cards. Unlocked is mainly for international use. Thank you for your interest,ClaytonMobilekarma

PUK is from your carrier, I believe. You can also look into your local or mail-order cell repair options for people with the proper hardware to support this operation.
