As we are all aware, contact information between you and your partner is very important when applying for a visa to the UK or Australia. This includes chat records and sms records.
As technology moves forward there are more and more applications becoming available, but it is always better to use an application that allows you to print information than using one that does not.
TheWhatsapp application seems to be very popular now, and used by many of my clients. It allows you to print off all of your contact information; so my advice is, if you are not already, it may be a good alternative to use this app when contacting your Thai partner.
