It's not that much, and to be sure, if you compare to the competition, PM is relatively cheaper, and still as reliable. PM can only do what makes sense, and what would be more easier to manage.
Example, some PPL on the Now Gone Canada-Wide Txt tried to use CERTAIN Short Codes, though Canadian, encountered the message, Sorry, But your Short Code Message will not work on Canada-Wide Txt.
The Global solved those issues, and to have a separate Canada-Wide would be pointless.
With Global Text (which is an included service with PM) is it possible for someone to be able to send/receive text messages while in a different country other than Canada? If so would there be any additional costs applied? For simplicity if was out of Canada would I be able to text back into Canada from UK or from UK to any other country?
The short answer is no, that will not work, and you will get no services at all (including text) from PM while outside of Canada.
The longer answer is that PM has no roaming agreements internationally, so as soon as you leave Canada, your phone will lose service. If you need services in your destination country(s), you will need to use a global roaming service such as iRoam (I beleive they work in the UK but have never tried), or purchase a pre-paid SIM from a local provider once you land in your destination country and use their services while away.
The Global texting option in the PM plans is to send and receive texts to international phone numbers but only while you are physically whtihing Canada.
EDIT: just realized I neglected to say: welcome to the Public Mobile community! Please let us know if you have any additional questions or concerns. And for quickest answers, it's usally better to start a new thread than to reply to other existing threads whenever possible. Cheers!
@manichauhan my pleasure.
I didn't want to overload you with info, but there are data-based ways you can sort of work around the problem of not being reachable on your regular (public mobile) phone number. If you're curious for more details and planning to buy service overseas that includes mobile data, let me know.
