The packages in Thailand only offer one connection (sim card), if you want more you might need to buy a WiFi dongle, and two sims, one for your phone and one for the dongle, the dongle will allow six or more connection.
Please be aware some jobs are only open to Thai people, (foreigners generally need to be professional or have a special skill) a list is available online.
you need to have a "person of standing" like village head, mayor, or a professional person like police man, doctor, I get a teacher to sign, they need to have a stamp of thier company. It needs to be done every 24 months, if in doubt call uk.gov there very helpful.
