Re: What is the difference between "cell phone" and "mobile phone"?
But what about this context? "I bought a new phone." I think this senetece might be ambiguous. People don't know if his new phone is cell phone or not because it can be home phone.
And second question is "Does "Ring me me back on my mobile" mean "call me back on my cell"?
Is it common expression in U.K and U.S.?
Sorry to bother you. (I hope you don't regard me as "pain in the neck")
You're definitely not a pain in the neck, Eureka!
It would be very common in the UK to say "I bought a new mobile" although, as someone has already said, they are so common these days people are more likely to assume that it's a mobile/cell phone than a home phone!
"Call me" is also very commonly used in the UK.
