OnlineTel is a Long Distance service provided by Wordline (Fibernetics). HQ in Kitchner, ON.
In our OnlineTel Review we found the characteristic is that defined of Call Zones; in which by paying an annual fee of $37.50 you have unlimited calling; albeit each call is limited to 30 minutes in duration, so if you want to talk more Onlinetel suggests you just call again.. These Call Zone are in Alberta, Ontario and Quebec. Similarly as Phone Cards you'll have to use a local access number
You can call elsewhere in Canada, though the rate for Canada wide Long Distance is a bit more expensive than our Top Long Distance Providers. There is no app for smartphone nor desktop at this point.
In all OnlineTel is an odd combination. Looks like an idea the market has simply outgrown; there is an hefty entry fee for Calling zones, which many Home Phone providers offer for free anyways, and international long distance rates aren't the best one can find and lastly there is no smartphone integration or even web calling.
