multiple recepients to one txt unreasonable charges

[Anonymous]

Ii have just had my bill which is double this month as I sent one txt under character limit to multiple receiptants & 02 have charged me 0.333 per txt! No icons, no pics just one txt to several people! I don't want anyone else getting stung by this! You have to forward the txt one by one as per 02.

I have the option ticked and it always triggers for me on a long text. It doesn't really matter though as I don't pay for mms

If the phone converts to MMS then O2 will charge for it, if not they won't.

Still a bit confused by this @MI5  Sorry, I am not disagreeing or challenging you ar all. I take it that the software which runs the messaging service must include a routine to determine if the conversion from sms to mms is appropriate.  So that leads me to wonder if O2 has any say in determining the cutoff point when ordering phones from the manufacturers?     If so why would they set different limits for different phones? 

I am probably missing the point as is so often the case.

My phone convert a text to mms after 480 characters which is 3 messages and sends it as mms for which O2 would normally charge. If a phone converted after 5 messages it's only then that O2 will charge.

It's entirely down to the way the phones software is written so nothing that any of the networks could control.
The same software will go into every phone worldwide and would be neigh on impossible to tweak it for every network.
In theory it could be something O2 put into their ROM customisation but it isn't anything that they do for any phone at the moment and would delay updates even more than mow......

Thanks for your patience @MI5    I must say I find it a very odd situation indeed. And it makes the O2 advice in the link here Stop SMS message going as MMS inaccurate.  If the cutoff point is brand and/or model dependent then mentioning 25 is misleading.

Thanks again for enlightening me, even though the sense of it still escapes me.

Hence my previous comment re writing a guide to cover all possibilities would be impossible.....
You just need to turn on any warnings that are available on the phone that you are using and keep your eye on them appearing.
