I use a couple of SIMs on a day to day basis – phone and iPad. The phone is always with me whereas the iPad is not. The iPad is also more likely to be used in an area where there is WiFi. Needless to say if WiFi is available this gets used in preference to 3G in any case – longer battery life, faster and cheaper connectivity.
The usage patterns are as follows:
|Month/device||May iPad||May phone||June iPad||June Phone|
|Bandwidth usage (Bytes)||320,270,336||1,241,365,504||262,217,728||662,842,368|
|Days out of office||6||7|
Clearly the phone gets used more than the iPad for accessing data. There doesn’t seem to be much correlation between days out of the office and usage though not that this small sample is particularly scientific. My days out are usually to London and typically I will leave my ancient laptop technology behind in favour of the tablet – lighter and good enough for most uses though not for any serious work.
It looks as if I am using between 1Gig and 1.5Gig of mobile data a month which is hugely more than the average of 200Megs (according to TMobile in January when they slashed usage allowances from 3Gigs to 500Megs). I may not be the average user but this must surely be the way of things to come.
