Can I come in at 7/11 and say I need unlimited for a month? And pay right there? Or should I tell them what the tariff is? I took for 1000 baht, if I throw 1000 baht now, it will last itself at the same rate?

Come to 7/11 with a passport and a SIM card, say that you need to extend for such and such a period, he will offer you options. We paid extra 200 baht for 2 extra weeks.
