Welcome to this user forum.
In order to find out what services and speed range you should be getting, please enter your BT Retail phone number into this form.
Broadband availability checker
Please remember to edit out your phone number before you post the results.
I assume you are getting dial tone on your phone?
Without a landline you cannot tell if you line is active and you just have problems getting infinity or you don't have an active phone line which is worse
a cheap corded phone is an essential 'piece of kit' so you can check you line status and also check for line noise which could easily save you paying £130 for openreach callout
Then try your new address in the checker and post results. Not as accurate as phone number but good guide
