Traveled from Hong Kong to the USA and ordered the computer and had it waiting for me upon arrival. That way  I could get to work without delay. Logged in using my Google account and in a few minutes I was working away, all my apps and extensions loaded for me. Haven't used it with a sim card yet, but love the option to do so if I take it somewhere where there is no wifi.It's been 2 years now and it has been a faithful workhorse, BUT in September I was on a trip to the Philippines when my screen suddenly developed a lot of lines. It is still functional, but irreparable. I went to the Acer Support Center in HK and they said that because I bought it in the US, it can only be serviced in the USA. When I bought it, it was supposed to have a 3 year warranty, but the service center says that once you leave the US the warranty is only 1 year. If I can find the part I can get someone to fix it, but not sure how to do that.
