Hi all going to get a telecom wireless ricochet system for my house. along with the smart com so I can control the alarm from an app from my phone. as backup I was thinking that getting a phone call on alarm would be good. I could get the standard voice messenger for £20 odd that connects to a bt landline . Or I could get a separate gsm module with sim that calls me independent of my landline. Either a texecom one or another recommendation for a tell gsm dialler. Both over £100 , texecom about £30 more than the tell gsm. Id rather spend a bit less but it strikes me if my landline fails then the internet will also fail and Id have neither alerting me on alarm. so maybe getting the gsm module a safer bet? Any opinions? How often do landlines really go faulty? is the gsm any more or less reliable than a landline anyhow? If it were a gsm module the texecom brand to match the alarm or a different slightly cheaper ( but recommended gsm tell module ?) All on power saver.co.uk. thanks in advance , opinions wanted.
