Steven, Jan,
Is it legal to send bulk automated SMS from SIM cards with a Smartphone or SIM box server?
When I read the Terms of Service of SIM cards (of MV but of any other operator like Proximus/Base/Mobistar), it seems it definitily isn't allowed.
ToS of Mobile Viking :Article 9
[...] Are already not considered normal use (non - exhaustive list): [...]
[...] use in a way that
differs significantly from the averages of the various customers of the Services in the areas of frequency, distribution among the different types types of communication (ie. telephone, voice, data transmission,
SMS, ...) or connection time; [...]
ToS of Base (unlimited sms offer) :To be able to guarantee optimal terms and conditions of use for you, our unlimited offers are
exclusively restricted to normal personal and private use. [...]
Your use will, for example, be deemed fraudulent in the following cases: [...]
- You send more than 350 text messages a day and/or 10.000 text messages a month; [...]
And so on... they all have in common the "normal and private use", Proximus even had a limit of 250 recepients maximum a month.
When you do bulk SMS, I'm quite sure this is not a normal usage ; especially in the case of bulk SMS to different recipients.
I'm using now a MV SIM card for bulk SMS even before I got aware of the ToS.
As you're software engineers working at MV, do you know if there is a possibility that my unusual usage of SMS can get noticed? ; e.g. could there be any algorithm that checks the number of different recipients per month an SMS has been sent to, or the number of SMS sent per month (I'm rather worried about the former: amount of different recipients per month).
Also, MV is using the SMSC of Base, so it would be interesting to know if something is in place at Base's side.
Let's say I send 2000 SMS per month with a MV SIM card, it costs me 15 €. If I use a third party SMS gateway like Clickatell & co (let's take an average of 0,07 € /SMS), this would cost me 140 €, so I'm doing huge savings as you can notice. If I use the SMS API of an operator like Proximis or Mobistar, then it will be even more expensive.
