Part set b , c and d attributes can be changed from internal , internal + external, look at the settings for it in manual can't remember where lol
The doc will be here soon if you don't find it
70 as in settings for d he might mean above
Well WiFi can be good depending on router type but consider this as an example , you could go quantam70 with a gprs card yes you have a contract but interns of network coverage it's better and you can use it via an app , the contract meaning for the securcom not necessarily a maintenance contract
Ok it won't do it , according to install manual
Get a quantam70 fitted instead with a gsmq but you will need a contract SIM if you enable all the functions and all the SMS options
