hi, I have two phones on my account, I know that I can talk unlimited with my second phone, but is it the same with text messages ? Do I have unlimited text message with my other phone wich is on the same invoice ??
I'm a bit unclear what you mean by "two phones", do you mean two plans? Because you can only use one phone per plan... but you can have multiple plans on one account. Everyone on the same account can call each other for free, true.
It depends on the plan itself though if you have unlimited messaging - the newer plans all have it, the older ones needed a add-on for that :)
