That should be the "Tim welcome home", but the only advantage (?) will be that calls between the phones that have the same plan (in Italy) the price is of 0,06 eur/min, similar to the "Tim Tribu" plan.
Otherwise, calls VS Usa/Canada/EU are billed at 0,50 eur/min like the "unica new" plan and for the other countries...well...reaaly expensive!!
From 0,80 eur/min to China to 3.-eur/min to Macedonie.

(Funny that from Netherlands, with my Ortel sim, the same calls will be repect. 0,12 and 0,30 eur/min!!)
