If a mast has say 800+1800 available under what circumstances would it not allow devices such as mobile broadband to connect to 800? is it down to the operator or mast config? as i do not see the point in 800 being deployed if masts wont let you connect to it.
Quite few. Capacity on each frequency is different. Three has only 5 MHz on Band 20 (800), and they have 15 MHz on Band 3 (1800). They also have around 10 MHz on Band 1 (2100) which you may also see.
Some information on Bands and spectrum owned by each mobile operator:

The mast can refuse you to connect to Band 20 if:
* You are a phone which does not support 4G Calling / VoLTE branded "SuperVoice" by Three
* You are a mobile broadband device and have a good Band 3 signal
It is down to the business policy configured technically on the mast. Each mast can be configured differently to cope with different geographical requirements.
Band 20 for voice calls has helped Three with indoor phone calls when they hope internet would be over WiFi. Many handsets also support voice calls over WiFi which also solves a problem.
