I don’t think they do pro rata uncapped so you are stuck until month end. However if you can’t wait that long just order a sim for R51 and you will have 7 days uncapped and do the bolt on uncapped package on this new sim which will kick in after those 7 days are up. Remembering to set your spend limit to avoid extra charges and then cancel it month end or continue to use this 2nd sim into the new year.
