We now provide you an easy way to estimate what your monthly cost would be if you upgrade to our Standard or Premium pay-as-you-go plans.
In the OMS portal, click the ‘Usage’ tile and click the ‘Estimated cost’ arrow to get your monthly estimated cost given your current data consumption.
With the ‘Free’ plan you get 7 days of data retention and 500MB of daily upload limit.
The ‘Standard’ plan gives you 30 days or retention with no upload limit and the ‘Premium’ plan gives you 1 year of data retention with no upload limit. The standard/premium billing – you 'only pay once' when 1 GB of data is sent. Its not a monthly recurring charge.
