I wouldn't rely on public mobiles data usage text to help monitor your data usage. I have never received one so I have no idea what they look like or how are accurate they are. But they are often sent out in error.
While your plan data counter in the self serve account is very accurate and an app can help you track your usage it doesn't necessarily prevent you from running out of data due to an app that's going crazy or accidentally disconnecting from Wi-Fi.
It's also important to keep in mind that data usage text from public mobile are sent out based on all of the data you have on your account so that would also include any add-on data you've purchased, any bonus data add ons or promotional data add-ons.
I have very little or no plan data on both my accounts. But I have been here long enough to have a lot of add-on data. However I do try to only use my plan data each 30 days. And I've only used about 1 GB of add-on data on each account in 3 years.
It would be a very expensive lesson for me to be in your position right now as that would be about a $400 mistake. To prevent this from ever happening I set my data tracker with the correct dates after renewal for my 30-day cycle. I then set my data warning at 25% of my plan data and my data limiter at 50% of my plan data.
I then increase these values once I hit my data limit to 75% and 95% respectively. When my data stops at 95%, that's when I decide what to set my limits at for usage of my add-on data. Usually at most that would be another 100 MB for my warning and maybe 200 MB total for my limiter.
Although that's unusual that I would even hit those amounts. I think I previously worked out that on average I may use 30 MB more per 30 days.
Figuring out reasonable limits for your data usage and implementing them by using your data saving tools in your phone will help ensure that this never happens again.
