W705 Tip #1: Data Charges
W705 users must take note of their data usage if you are using the Play Now Plus features to download free songs from Sony Ericsson. Each songs is around 2MB to 5MB and therefore you will using a lot of data usage. You must ensure that you have a data plan if you want to use the Play Now Plus. Play Now Plus is available on Singtel W705 sets only while M1 and Starhub W705 only has the Play Now.
It is your responsibilities to ensure you have a data plan and do not assume you have it with the plan when you bought it. There are some Singtel users who have incurr high data charges when downloading free songs from Play Now Plus as their plan did not comes with a data plan. The songs maybe free from Play Now Plus but if you do not have a data plan, you will need to pay for the data downloads.
I have a Data Plan of 50GB from my Singtel Corporate Plan at $7 only. Normal data plan will start from $3.21 depending on the data plan you are subscribing to. It is best to take up a data plan with min 500MB data and above. If you are not downloading songs, then a data plan of less than 200MB may be sufficient for your usage.
