So, long story short. I received an email today mentioning that I had breached the conditions and I would be terminated within 7 days.
I suspect this is not the case, and they are just kicking people off that are using high volumes, as I'm running it in an old Huawei Y550. I've only used 200GB which is roughly in line with what I would use when sim-slutting anyway. I was paying an extra $15 or so just so I wouldn't have to change sims constantly, but it looks like that was a dumb idea.
I'm giving them a big middle finger to the Felix Mobile team because frankly they make it unclear what is a profitable and unprofitable customer to them. I hope their business model fails.
I'm in the Inner West of Sydney, so I'm lucky enough I don't have to put up with them with all my options.
Thanks.
I think.
