Hello I am Samuel and I saw your question. The answer is no unfortunately. The device is built for 2g so even if you add a 3g card to it it will not know how to use it. This happens from time to time when they upgrade the networks. I am sorry about it. If have questions you can call me or respond to this message!
Is there any other help you need? If not please rate so I can close this request! Thanks so much!
Rate here sorry.
