Does this support Sontel Sip Voip service outside the US? Is it unlocked?

The device is definitely unlocked. It should support any service that can be supported using other sip clients. if you are able to connect to that service provider outside US (specially from the location you are planning to use it, say using a softphone, then this device should also work too. At the end of the day, it is a softphone embedded on to a chip).

If this phone is unlocked internationally from Sprint then you can use it outside USA.

I am not sure. I researched it and I am under the impression that carrier unlocked phones still have software specific to the carrier, where the factory unlock does not tie to a specific carrier. I am not sure that I understand this fully and do not know if it can be used out of the country. Sorry!

This phone will talk with standard sip accounts. I normally use this with asterisk-based pbx to talk up stream to voip providers. The question to ask your voip provider is do they support sip handsets such as the grandstream or only with pbx systems.

It is not an unlocked phone. It is a Net10 phone. It only works FROM the U.S.

Yes it can be used out side the US, but make sure before you go that the phone is in a working order.

No, but you can call 1 (800) 711-8300 to try and have it unlocked for global use.

You must ask the seller specifically. My friend bought the unlocked, international version and couldn't get voice mail on AT&T; as the phone wasn't pre - loaded with AT&T;'S own software. As I explained in another review, it's a great phone for international travel, but not ideal for US usage. I have heard, though, that T-Mobile works well with this phone.

This model DOES have a SIM card, and it IS the global model; so, if you have the correct contract, the phone is capable of handling calls outside of the United States. However, this is not a satellite phone. So, if you are just asking about roaming globally, then it will not work.

yes you will be able to, inernational phones are open for all companies that use sim cards and you can use them world wide, you will get updates before US owners.

The phone is unlocked. The version I got is only good in the Americas (North America, Central, and South). It is not recommended for other countries.

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.

I've never used it out of the US - I have received international calls on it. While I can get to facebook, google and youtube - in many cases it is in limited view. Just tried downloading skype - it's too large for the phone's capacity.

I'm not sure about internationally, but yes its unlocked, and it's a nice phone.
