I have a Fido phone (unlocked - ex SO) for my son and a SO phone for me... because my son needs a lot of text messages I am paying $25 to Fido... the new bundle of $10 for 2,500 messages from SO it's much better because he is hardly speaking on the phone. If I buy a SO SIM, after a few month Fido will deactivate my Fido SIM and it's no good anymore if later on, the deal from SO will disappear... if someone needs to talk and text the $25 deal from Fido is very good (100 min. billed by the second + evenings and weekends free + unlimited messages) but he needs to buy a SIM card from them... anyway, I am trying 😆
