Hi there,
It should be absolutely fine however you will need to be careful how you place your order. As the original property has had service before you may be sent to quick starter kit but you will not be able to use this because you are in the Annex. Does the Annex have a separate address or is it just the same address?
The best thing to do is speak to Christy above as he is an expert in getting these things done correctly. Thank you for your interest in joining us
