Perhaps you haven't taken a look around the site, but the catalyst of this program is posting roll...Every.Damn.Day.
If you won't have internet access, then text someone before you leave and ask them to post for you for "x" days, promising them that you will stay quit.
"I have had one person offer me his number". And how many people have you PM'd your number to? There are 40 active posters in September, reach out to them. They are new here too.
It's simple, you get your name on that roll every day, somehow, no matter what. If that's "not how you roll", and you want to bypass the methods which are the catalyst of this site, then you can piss off. Sorry, but you are not special. We are all addicts and this is the foundation of quit here.
