Changing phone companies

Yes, it's standard procedure. For landlines most operators do it for free, but they can charge a small fee ( like 5 or 10 euros think). For mobiles it's always free.

Not always as i found out to my cost proximus promised me i could keep my old one when we switched to them but that was a lie they got it wrong in store checking and because they then didn’t know how to resolve this they just never turned up to change my line over its was a complete nightmare.o had stayed in all day took weeks to reslove In the end i had to aggree to change of number as i had taken a low price TV in my pack that was now not able to be returned i could tell them to just do one. Oddly i had moved into that house with a different company and kept my number so that also was kind of difficult to understand I now have a number linked to the next commune 016 rather that 02 my commune because i live near the edge of the commune. Be aware its not always simple.

Nonsense.
