If you're getting close to your data limit, you can easily add more data by topping up your current aloSIM plan.
Select "My eSIMs" and then select the package you'd like to top up. There should be a blue "Top up eSIM" button that will allow you to select a new package.
For example, if you have 0 GB of data remaining and three days left on your plan, you could buy a seven-day plan with 3 GB of data. That would immediately give you 3 GB of data to use over the next 10 days.
