Dongle & Wifi Broadband

[almaca]

I am looking for an explanation of what is provided with a Dongle and Wifi broadband. A friend presently has PAYG only but hopes to switch to monthly contract and specifically the contract which provides 75GB of data and 100 texts per month.

What I need to know is: 

1. How do you know when you've reached 75GB of usage, and what happens if you exceed it?
2. Does some of your monthly payent include mobile 'phone usage and is the 75GB data allowance reduced in relation to how many calls you make?
3. Can you change settings so that it is impossible to exceed the allowance?

I tried 'phoning o2 but, when I eventually got through, they didn't seem to be able to answer the above questions.

Thanks.

Data just stops when you reach your limit so you cannot exceed allowances.

Data only sims do not include any voice calls but you get a free bonus of 100 texts.

Hi MI5,

Thanks for the information. Does this mean that the existing PAYG SIM can continue to be used and topped up as necessary. I presume the Data SIM is then inserted in the dongle?

The person I spoke to at o2 mentioned something about a £10 charge if you exceeded your limit but she didn't seem to know much about it herself.

Yes the data sim goes in the dongle and the other PAYG sim is used as normal.

No idea where the notion of a £10 charge comes from, sounds like they were guessing rather than checking their facts.

Thanks. That helps explain things. Is there any comeback if you take the 2-year contract and then find that the signal is so unreliable that you can't use it ?

You can cancel for free within 14 days if it's unsuitable, but after that you are responsible for the full term of the contract.

Okay, thanks. Thanks good to know.

No problem.
