I am a senior on a limited income so I feel I get more value out of home internet with unlimited data then I would by just having it on cell phone . My high speed home internet costs me $75.00 dollars a month . I live in Canada. I feel that having it on cell phone with unlimited data would cost me the same or maybe even have a higher cost . I cannot afford both . My cell phone operates on a sim card and can pick up free wi-fi which is offered at most locations where I shop and I can use internet when I am at home . I use 7-11 speak out and since I have a home phone as well I do not make many calls on cell it is mostly for emergencies, if I am out and about . Last year my cell phone costs averaged just under $4.00 a month . Any speak out card you purchase is good for 365 days no matter the denomination .
