Which country's market was my phone meant for? I have a phone with Android 4.4.2 (CAT S50). It is of unknown origin (meaning, I don't have a slightest idea whether it was sold in US or in Japan or somewhere else). I'd like to find out what is the country of origin (the market it was supposed to be sold on, to be more precise) for this phone. How can I do this?
It is not meant for any specific country as per their website. 

3G and 4G details show that clearly by mentioning North America and ROW (Rest of World). No mention is made of product variations for different regions/ countries, so it's tough for you to find out where it was sold

AFAIK there is no way to determine where the phone is meant to be sold, IMEI gives country of origin (exception is Samsung, which assigns different codes to countries/ regions)

Edit: OEM website specifically has a flyer saying that s40 is meant for US markets. Absence of any such indicator for s50 strengthens the case for "no specific market"
