It is certainly not something that I would suggest as a full time solution, but there are definitely times when using your mobile phone as a modem is a good idea.
Why though? If you have an internet browser on your phone, why go to the bother of connecting it to your computer and using it as a modem? There are a few reasons, which include:
1) It can be easier if you are sending lots of emails to type with a proper keyboard.
2) Sometimes the software just doesn’t run on a mobile, for example if you are FTPing files.
3) Convenience of keeping 1 source updated or viewing a bigger screen.
What are the problems? Well first, whilst the phone is in use as a modem you probably can’t take calls. Secondly, if you go outside of your monthly allowance it could be expensive. For me, after my free allowance has expired it is a maximum of £1 per day for data usage, so I am not all that bothered. Much cheaper than an internet cafe for an hour or so!
Why not then just buy a USB dongle? You can do, with the same effect. However, a USB dongle doesn’t use your free allowance; the dongle costs money and may be more costly if it also needs to go into a package.
So, how do you turn your mobile into a modem? If you have an Android then my recommendation is to look for the PdaNet App on the MarketPlace, install that and follow their instructions. I spent two hours trying out different Apps and this was the only one that worked for me, without so called ‘rooting’ the phone.
They have some software you must install on your computer first, so some planning is required, but the entire process must have taken me less than 5 minutes.
Then it is just a matter of turning it on, both on your phone and your machine, and you can then browse the net from your computer. You are limited to 3G speeds, so not a permanent solution, however, having said that if your phone is registered to a WIFI network that your machine can’t access, then this can also be shared this way. Very useful for those certain “free” WIFI spots where you can only register the one device.
