Hi I have run out of data and need to top up data now if I change my
tariff now will it go on straight away or do I have to wait until the
end of month when my next lot of GB is due? or should i add bolt on til
then? thank you
Ill add a bolt on until my next official tariff date which I have now
done so I have plenty of data. I am now using Waze for my new work and
its using alot of data now. Thank you for your help
