Hi Rustad
In my case it was all sorted within a week or two max. Just remember they won't come out until you pay them the installation fees upfront but you can sort it all out online and/or by email. Just remember to order the wifi modem if that's what you want and is the slightly more expensive option of the two. Further to receipt of payment they can usually can organise an appointmemt date within another week but you or someone has to be in on the day.
A2Z generally only install in Condado on Tuesdays and Thursdays and be prepared to wait in most of the day. However once you're up and running it'll be well worth it.
