How many devices should you buy?
When planning to purchase devices for a project, it's advised to buy an extra 10% on top of your total user count to compensate for potential losses, breakages, or for use in training and technical support. Historical data suggests a 2-3% rate of loss or theft over three years.

How much data should you purchase?
Many projects find that a monthly data allowance of 100 MB is sufficient. To estimate usage, consider that each form submission is roughly 7-10kb. For instance, submitting 20 forms daily over 25 working days requires about 5MB per month. For example, for a project where the FLW submits 20 forms a day, 25 days a month: 20 forms x 25 days a month x 10kb/form = 5MB
How will you charge your devices?

Solutions include home charging for those with electricity, providing solar chargers, or establishing central charging stations, which are cost-effective but have higher theft risks. In some cases, reimbursing charging costs may be necessary.
