I recently noticed a 1GB promo data amount in my self-serve panel. I am currently using the 15 dollar plan with autopay which also gives me 250mb of free data.
Will this 1GB promo renew every 30 days like the other 250mb?
Probably only a 1 time promo such as Holiday Bonus at Xmas season. Usually, recurring data incentives are targetted for new customers to get the $25 plans and higher.
Even if you do opt to upgrade to a higher price plan...that 1 time data promo amount will stay until you use it up, even if that take several months or more.
Like others have said, you'll have to check the Terms & Conditions, but it's highly likely a one-time bonus. I can't say I've really heard of a 1GB Bonus for the $15 plan (unless it's those Holiday freebies so I'm glad you got it!
Those add-ons usually roll-over from cycle to cycle until used up, then it disappears from your account altogether. I'm guessing that's the case here. If you have troubles specifically with this, you can message staff, but I'm pretty confident that it's a one-time bonus.
If you have specifics you're still questioning, just give us more details and we can give you some more thoughts! 🙂
