Recently, I went through my bill with a fine-toothed comb and I’m certainly glad I did. Had I not done so, I wouldn’t have realised that I was being charged for messages I did not ask for, did not subscribe to, and most definitely did not click on to initiate.
Given that the device they came to is in fact, an EE 4G modem, that would prove somewhat difficult.
To respond to messages, it is necessary to log into the device, talk to it via http, click on SMS and in other words, go out of your way to do so.
The device itself has an absolutely huge amount of buttons… Two.
Power, and WPS.
With those, it is impossible to send, receive or even view texts, so I call BS. I call it loud and I call it clearly.

What this boils down to, is that the below email is completely, utterly, totally, inarguably BS of the highest order and I’m posting it here publicly so that people are made aware of the lengths companies will go to, to make money.
Avoid GamesHaus in any shape or form wherever possible, and tell your friends and family to do so as well.
They are disreputable, they cheat and they succeed in spamming people less diligent than I am.
If you happen to have a device such as the EE Osprey or Osprey Mini and you think ‘surely nobody would be silly enough to send texts to it or expect me to respond if they did’ check and check again. Check your bills and out-of-plan charges to be very sure that this is in fact, correct.

Hello ,

We have received a request from your carrier asking us to email you
regarding a complaint.

You have successfully been unsubscribed. Please find a free message on your
handset confirming this.
For your convenience I have blocked all future initiations from this number.

Using your device you have clicked on an advertising banner which was
advertising the GameHaus subscription service where you can access and
play browser based games on your smartphone or tablet.

Once selected the payment page is then displayed, where it detailed the
cost of joining the service and the weekly subscription amount, and the
help desk number.

There is also an icon of your mobile telephone carrier with the words ‘pay
with *your carrier* ‘ next to the icon.

Once the ‘SUBSCRIBE/PAY NOW/PURCHASE’ button next to the payment
information is clicked, only then are you subscribed.

The next page advises ‘you are now subscribed’ and how to commence using
the service

If you are requesting a refund I am able to have a once off refund provided
via PayPal.

Please provide your money received PayPal address.

As our initiation sequence has been completed directly on the handset, is
compliant with the industry guidelines and endorsed by your carrier (our
third party billing partner) and each of the messages we have released to
this number as an active member advise of our help desk number and stop sms
number future refunds can not be offered.
