Parakeet - data roaming problem

[bordeb]

We are using Parakeet for almost a year without any problem with the EU gprs roaming (we were several times in Slovenia, Italy without any data roaming problem ) but on our last trip - last weak we had the huge problem with the EU data roaming (nevertheless, sms worked normally). I am not sure that the general problem started exactly last week (we are not traveling so often) but we noticed the problem last week on our trip to Slovenia, Austria and Germany. The problem was that when changing a country (roaming to a new country) the parakeet could not initially connect to the internet in any new country, although there was NO problem with the ISP money/account/subscription - that was 100% ok. The problem could be resolved only by taking out the sim from parakeet and inserting the sim in the regular smartphone and than start the phone with the parakeets sim inside and then put the sim back to parakeet. After that everything started to work again. That was repeated each time we changed a country and there was no solution beside mentioned dismounting the parakeet, taking out the sim, putting it in the smartphone and starting the smartphone with that sim inside and then put the sim back to parakeet, when all starts to work without problem. So, to sum-up, after changing a country it is impossible to use the internet on sim in the parakeet without first starting that sim in the regular phone.
My understanding is that the parakeet can not accomplish some "new initial procedure" that is required from the GPRS operators and after "that procedure" is accomplished using any regular smartphone (but unfortunately not the parakeet itself) the GPRS internet starts to work normally (even in the parakeet), until you change that country. To be sure, I tried with 2 different sim cards (I have the reserve one) and the issue was exactly the same. When we turned back to home county everything worked without the problem (taking out the sim from parakeet was not necessary any more). This is probably because it is the home country of the sim. Any help would be very appreciated!
