Global SIMs and Push Messages

2 years ago I went half livaboard (6 months on boat and 6 months at home).
At that time I switched my mobile to a ‘global’ SIM (sim4travel).
It works well for me. No incoming charges in Europe, most calls out at 25p min, and cost to people in the UK calling me, again 25p min.

However, I’ve just discovered a snag......I have opened an online bank account with Abbey. They have a security procedure I have never come across before. They have a system called One Time Passcode and the way it works is like this. When you want to make a payment, they instantly send a text passcode to your mobile phone. You then enter it online into the payment details you are setting up, and hey presto, the payment goes through.

Sounds like quite a good system...........except that they send the passcode by a system call Broadcast or Push Message. Apparently this is the system people use for sending spam texts....and yes, you’ve guessed it, sim4travel do not accept this type of text.

So, the question is, does anyone know of any similarly priced ‘global SIMs’ that do accept Push or Broadcast Messages?

Incidentally, one other problem if anyone is thinking of opening an online Abbey account, is that almost unbelievably, they don’t support Internet Explorer 8, so you have to download Firefox! To find that out, you have to negotiate what must be one of the most frustrating call centres ever devised by man, and eventually, if you are really persistent and have the patience of a saint, you end up talking to a REAL PERSON, albeit in Delhi, who might finally give you the number of another call centre in Belfast who seem to know what they are talking about.

As you can gather from my tone, my experiences over the last few weeks have not made me an Abbey fan. Heaven knows what they will be like when they are fully controlled from Madrid!
 
Hi CaptainCava,

I'm not sure I recognise the problem.

My guess is that sim4travel is just an MVNO that has roaming agreements with a number of operators elsewhere. Although their website claims they operate their own network, the fact they mention support in 36 countries is a give away.

Are you certain the bank is sending an SMS text?

The normal way is for the bank to have a connection with a third party operator (probably somebody big like Vodafone, O2 etc, but could be abroad). They'll send each individual SMS onto the SMSC (SMS Centre) belonging to that third party - probably using SMPP (Short Message Peer to Peer) which is the dominant protocol.

Because you are roaming, that SMS itself won't even touch your home network. The sending SMSC contacts your home network HLR (Home Location Register) to find out where you are and then sends the SMS directly via the MSC (switch) on the visited network.

Because of this it is very difficult (pretty nigh impossible) for sim4travel to filter your SMS. The whole control of SMS spam relies on the originating network trusting the people they give SMPP connections too.

Have sim4travel confirmed what the problem is from their side?

MMS is significantly different and that does allow broadcast. Push is a term that also makes me think MMS. Of course the bloke who explained it to you may not have had a clear understanding himself so I don't want to read too much into that.

Your best bet is probably to contact sim4travel and have them investigate. Make it clear that it is likely to affect whether you'll remain a subscriber. That's likely to focus their mind.

In fact nothing to do with Madrid, thank goodness, but in rational N Spain.
It's probably one of the most solid banks in Europe (unless you include HSBC as European).
 
We bought Sim4travel a couple of years ago but experienced lots of connection problems. Finally I called them from Greece, to find that it would not work with several Nokia phones, of which mine was one. They sent me a workaround that was so complex and intermittent that I gave up.

I had that with Global SIM It wouldn't send the call setup messages. I had to get a cheap mobile from ebay to make it work.

The service was poor - long delays on the line. Later it wouldn't transmit DTMF tones (the beeps you hear when you dial) so I couldn't work the answering machine. I abandoned it in favour of local SIMs.

(That was all before they went bust and got resurrected. I have no experience of them since.)
 
I have had the same problem, the Abbey/Santander passcode system does not accept Spanish mobile numbers. After an incredibly frustrating time negociating their "help Line" was told must I have a UK mobile. Needless to say I will be transferring my dwindling resources elsewhere next time I visit the motherland. (but only if I can prove my identity!!)
 
My guess is that these are ordinary SMS messages. Because they come from a computer, not a phone, the networks probably have to specifically allow Abbey to do this. (Perhaps that is the origin of the claim about spammers - networks perhaps reject computer-generated SMSs from unknown sources.)

So I expect Abbey have an agreement with all the UK-based networks to accept these SMSes. And this probably doesn't include sim4travel which I think is a Jersey-based callback service. It probably won't work with any other callback service either - the so-called 'international' SIMs.

If you're abroad you should get these messages if you're roaming - though delivery of SMSes is never certain. If you live abroad and don't have a UK mobile you could get a cheap or free prepaid SIM specially; after all you know when the messages are coming so you can stick it in your phone just for the occasion.

But, as I said, I'm guessing.
 
I'd be very surprised if they aren't SMS messages. There's nothing casual about the sending of bulk SMS. Abbey will have an agreement with an operator somewhere in the world, which will include an arrangement for Abbey paying for the use of the service.

Spam (real spam rather than irritating messages from your own operator) tends to originate via unscrupulous operators in small third-world countries, and even then if there's too much the big operators will put a lot of pressure on them to stop it.

You could get small scale spam via the likes of Skype or operators own websites but even then the sender usually has to register. Abbey won't be doing that (I hope!).

So what I'm saying is that Abbey will have a definite arrangement to send these SMS. After that they should get through as well as any other SMS. (If you have a spare few days check out TS23.040 on the 3GPP website - http://www.3gpp.org/ftp/Specs/html-info/23040.htm - for how SMS are delivered - it's actually one of the better standards.)

My suspicion is that the OP was fobbed off by someone with a few buzzwords.
