Please advise that below mobile will work in Canada.
Nokia 501 GSM : 850 / 900 / 1800 / 1900
Q Mobile Frequency / Band 900/1800/1900
Nokia 501 supports 900 MHz and 1800 MHz only as per Nokia website (http://www.nokia.com/global/products/phone/asha501/specifications/). So, it will not work. There is some info I found in TripAdvisor about using your existing phone in Canada. If interested read thru...
Canada Cellular Phones (Mobile Telephones)
Mobile phone service, or cellular, or cell phone service in Canada is the same as the U.S.A., but different from that in the rest of the world.
If using your phone from home, roaming charges can be expensive. Check with you service provider if they offer any roaming packages.
Systems:
There are 2 basic systems, CDMA and GSM (including AWS, UMTS, HSPA, LTE). GSM is used in most of the world but the North American system uses different frequencies.
AWS / UMTS / HSDPA are regarding as 3G. LTE is 4G.
Foreign CDMA phone can only roam on Canadian networks. Please check with your own service provider at home regarding compatibility and rates. The following do not apply to these phones.
All networks in Canada currently support one or more of GSM / AWS / UMTS / HSDPA / LTE . North American GSM uses 850/1900 MHz , UMTS/HSDPA 850/1900 Mhz, LTE 1700/2600, AWS 1700/2100 frequencies, which are not compatible with phones used in most other parts of the world except USA.
If you have a phone from USA, it should be compatible with the Canadian networks.
From other countries, you must have a tri-band or quad-band GSM phone, or 3G phone supporting 1900Mhz to be compatible. AWS phones (other than the Google Nexus) are not usually sold outside North America. LTE from outside North America are not compatible but these phones usually have GSM frequencies that are still compatible.
If your phone is compatible, it must be UNLOCKED in order to use a local SIM card. Phones are usually locked so you can only use them with a SIM from the service provider or carrier who supplied the phone. Phones can be unlocked to accept SIMs from other carriers.
A pay-as-you-go SIM card is $10 from most major networks. If you have an iPhone, you can obtain a SIM card from Apple Store in Canada with special pricing.
Local calls are ~$0.30/min and Canada long distance ~$0.40/min
