Is this phone unlocked?

If you are buying a used Polycom I don't think there is a way to know if it is unlocked other than the explicit assertion of the seller -- assuming he/she even knows. If you are not clear on this point get a new one!

These phones aren't locked but may be running a version of the OS/firmware that isn't compatible with your system. In that case you just need to force an upgrade/downgrade. We've done it with several phones.

Yes, these phones can be used with a multitude of SIP providers and systems. We personally have deployed these using OnSIP using their polycom boot server. There are however different sellers here on Amazon and I cannot speak to what the seller may send. They may arrive completely open and unprogrammed as we received or programmed for a specific service. The phones can generally be unlocked if pre-provisioned by using a key combination while the phone is booting. Check the user manual and google. Your mileage may vary.

No, it is not unlocked. It doesnt have a sim card slot. If you want an unlockable phone, do not buy this one.

No this phone isn't unlocked, it will only work with virgin mobile. Just go to the virgin mobile website and follow the instructions inside the box and you should be good to go.

It is unlocked. Using with my T-Mobile account. Works fine for me in the U.S. I do not know how it would work on other providers or outside of the U.S. Love the phone!

Yes it is. Its unlocked, but I don't recommend this model, it gets hot and hotter when you use for a long time... like a long call or something like that.

I do not believe it is unlocked! It is Verizon though, but please call them to find out if it will work with their prepaid plan.

I believe it is. This phone was purchased for my daughter who currently resides overseas; this phone was purchased when she was home for a visit that she could bring back with her. She needs an unlocked phone where she inserts a card for phone service, which I think is a SIM card. I hope this information helps.

The phone is unlocked. You can you any sim card from any provider and you do not have to contact you phone provider.

No it's not. You have to buy a SIM card for it. I have also heard that you can call Verizon and buy an unlock code for the phone.

I bought it unlocked, but if it doesn't say unlocked it's not. I bought another one from Verizon and it's impossible to unlock :-(

I'm not sure if it is unlocked, but I'm using mine with a straight talk SIM card if that helps any.
