I have my UK-based Android smartphone, but yay for Orange (sarcasm), it's locked and will take 3 weeks to unlock! Fortunately I also have a low-tech Nokia - I just need a sim. Rogers quoted me $70 CAD to get up and running with a pre-pay sim. Given it costs about 10 pounds in the UK to do the same, this seems pricey. Any suggestions for pre-pay sims (I don't need data, just text and phone). In Vancouver.
With Fido you can get a pre-pay sim for $10.
There are a variety of prepaid rates available. Personally I use the $10/month rate. You can change rates whenever you refill your account.
From Google it looks like there are plenty of Fido stores in Vancouver. So you could pop in and pick up a sim when you arrive.
The Fido website is good for managing your account. Note that I did have trouble refilling my account via the website using an overseas (New Zealand) credit card. If you have the same problem you can always buy refill voucher from a Fido store.
7-Eleven sells SIM cards for $10. They are a MVNO reselling Rogers service. Their main attraction is that prepaid credits are valid for one full year. However, it is not available for sale in all provinces (notably Quebec).
The price sounds rather high....
A price of $70 sounds like it includes a phone too. I'd suggest trying a bigger Rogers store and hope you get someone more helpful the 2nd time!
(You can also get new Rogers Pay As You Go SIM Cards off ebay for around $10 too, including shipping, which does look like it's the correct price)
