Sorry about the following rant. but it is a summary of my experiences with Rogers and Telus over the years.
About Rogers, if your cell phone is happening to be sitting near some powered speakers, be prepared to hear some funky interference noises when your phone communicates with the cell site. Be it your computer speakers, home theatre speakers, whatever. It is annoying. With telus phones, you don't get that.
With Telus, I got poor coverage where I live. I cannot make a phone call from my house using my Telus cell phone in digital mode. The phone always fell back to analog and it takes about a minute before I hear ringing. Could be the phone. It is a Motorola V8160.
With Rogers, I can make phone calls from my house no problem. But sometimes, when I'm on my way home and somebody phones me, the signal is lost partway through the conversation. Could be the phone, it is a Motorola V551.
Originally, I signed up with Rogers about 10 years ago and switched to Telus after hearing the quality of the voice calls on their cell phones in comparison to Rogers. It was crystal clear to say the least. Then something happened... the voice quality one day started to suck. After some searching, I learned that they sacrificed voice quality for call capacity (ie. they reduced the voice quality so that they could service more customers in a given bandwidth). That pissed me off. If you want to hear the difference, just call up customer service... they always give you the best possible quality when you phone them.
Telus wants money everytime you change your plan and they will *reluctantly* do plan matching. The CSR said that they do not plan match but I knew better since my friend just did it. In the end, I had to talk to a manager over the phone to get them to match a Rogers plan and they charged me $25 to do it... plus they renewed my contract for another 3 years. With Rogers, it's no problem the last time I did it... when I was originally with them).
Rogers billing is confusing. They have a weird way of coming up with the totals. I am on a $25 family plan and I added on call display. Nowhere on the bill do I see $25. Instead, I see different numbers get added on, then taken off, etc. I guess if I tried hard enough I would be able to figure it out, but since the totals match, I'm not worried.
When I re-signed with Rogers, my first bill came out to about $300 with all the fees and cost of the phones, etc. But they screwed up because they said that the first couple of months I get free messaging, voice mail, caller id, local calling, etc... So here I am messaging to my hearts content and when I get the bill, it turns out that they charged me for all of those *free* featuers. Good thing is that the CSR was happy to correct the problem, bad thing is that they didn't understand the bill either when I told them what my plan was.
Telus PERKS are good. I've used them to get hats, T-Shirts, hotel rooms in Vegas, etc. If you stay with them for 5 years, they will even send you a gift (in my case, it was a hands free set worth at least $30).
The last thing is that your Rogers phone works via a SIM card. Theoretically, you should be able to take your phone to another country with a GSM network (ie. United States, China), plug a SIM card local to that country and be able to make local calls (as opposed to long distance roaming). However, since Rogers locks all their phones (ie.the phone only uses their SIM cards), you will not be able to do this. Good thing is that you can unlock the phone at an independent phone retailer but it will cost you money and probably void the warranty on the phone. I asked a sales rep at a local Rogers store and they said they could do it, but they wanted my first born in order for it to happen.
Anyways, that's all I can think of. I hope this information is useful for you. If not, I hope it was at least entertaining ;-)
