Many thanks for posting. I'm so sorry to hear your mobile signal isn't very good in Ipswich. I'll happily take a look at this for you.
I've managed to locate your postcode to check the signal in the area. I can see there is a new mast being built to the East of you behind Stock Park Drive. I'm afraid I don't know how long it'll be until that is operational.
Signal can be affected by many factors as is outlined on our signal checker site here. To provide further assistance, could you please answer the following questions:-
What handset do you have?
Do you have trouble with calls and texts?
Do you get a better signal away from home?
Regarding SmartCall, it is free to download. It works off a Wi-Fi signal and is linked to your Virgin Media home phone package. To see what line rental packages we off please see here. For further information on what SmartCall is and how it works you can look here.
