Some plans will claim it's an "unlimited texting plan" but really the charges are still there hidden. Maybe the provider has an agreement with other mobile phone providers to reimburse them for texts their customers send.
My last provider refunded the cost if I forwarded the message to their spam department text number.
We have pretty terrible mobile phone plans and rules here in Canada.
That sounds very generous for a pre-paid plan. Is it unlimited for all incoming phone numbers or do you choose specific phone numbers?
I've seen plans that you choose friends or pay more but in some way you are paying more for the free part a bit like insurance. Maybe plans with unlimited texting versus regular plans are more common so the extra cost is seen as normal?
Hopefully it's changing or maybe texting is becoming less of a thing due to more mobile Internet access.
The worst part is here in Canada we have to pay for incoming texts.
