I'm not from your country so can't comment on any laws you have or how your networks work
It wold not surprise me that your phone have been deliberatly forced to log in into jewish network 
The only way to find out next time is to use application that will log the BTS (The Base Transceiver Station aka phone mast) your phone has been talking to e.g.:

Ther are couple of apps that look for IMSI catchers as well

but root is required:

Just out of interest, what have you been charged for? Data/Voice/SMS?
Is there a huge difference in roaming charges between those two networks?
I would as well ask Zain Jordan what network was it taht you have roamed in and then check their coverage as well.
Next time get local throwaway SIM card in roaming to aviod extra charges (with the D6633 you can have on 2 at the same time)
Ask for MCC/MNC code of the network in question:

Strange, but the Jawwal Uses the MCC of Israel !!!! Their friendly neighbour got near full control of everything there......
Get details information from you operator, dates, times and what it was for.
I know this is not going to help you, but this is interesting article that may give you inside of what may be going on:

Are they all incomming calls you have been charged for?
See if you can get hold of the CEO of the Zain Jordan or Zain Group directly http://www.zain.com and explain to him what has happend, what you have done, who you spoke to about it, where you have been, how long etc.
Check on the internet what is their e-mail address format "name.surename@zain.com" or other then find name of the CEO and drop him/her e-mail.
For you as an idividual it will be hard or imposible to prove that it was not error on your part, especially with neighbbour like this:

Sad to say but there is nothing that anyone overe here be able to help you with.
