First of all, let me state that I know close to nothing about cell phones.
I might be interested in purchasing a quad-band (GSM), dual-SIM card cell phone. The idea is that if I have to travel to a European country I could purchase a second SIM card there and install it in the cell phone.
1) What are the caveats about purchasing such a phone? For instance: Will the cell phone monitor incoming calls to either SIM card phone number? What about using SIM cards from two different providers?
2) Where would I find an online site that has tested and recommends particular brands/models? Paramount for me, besides cost, is voice quality, ease of setup and use. (I only need a phone that handles voice and text, so I am looking for a basic phone.)
3) How do I know if a phone for sale is a smart phone or a standard cell phone? For instance, is this a "regular" cell phone or a smart phone? http://www.cells4u.com/Samsung-E2222-Unlocked-Phone-p/sgh-e2222-grey.htm
4) Can you recommend a basic cell phone with the characteristics that I mentioned?
