In a remote study we conducted a month ago using participants in France, Austria, the Netherlands, and Italy. We found that virtually all the participants entered their phone numbers the way that they are used to, ignoring all instructions on the form. Participants in the countries tested just did not worry about the format they where entering the information in.
This study had a very high n. The participants would then edit the phone number when it failed the validation. The solution is to allow the user to enter their phone number in any format, and then convert it to the way you want it stored. So go with Option 2. Some participants entered the number with a leading +, others with leading 00, others with just the area code and the number. It is possible to parse phone numbers, but it is hard. The is because country codes have between one and three leading numbers. For example the US is "1", the UK is "44", and another is "353".... Some participants just start with the country code. No + sign, no leading 0's. If you go with the option 2, watch out for Italy, and the old Russian countries, as they some weird number formats for phone numbers.
