North American and Canadian networks operate on 850MHz and 1900MHz frequency bands, which are not the frequency bands used in Europe. In case you are a frequent traveller to different countries, along with a Talkabroad international pre-paid SIM card, you may consider buying a Quad-band mobile phone, which works on all the GSM frequency bands used all over the world, or at least a Tri-band handset which will work on 800MHz, 900MHz and 1800MHz frequency bands. On the other hand a Dual-band phone will work on 800MHz and 1900 MHz. If you are infrequently travelling abroad, you may consider renting a compatible mobile handset.
