Will my unlocked iphone 5 running ios 7 beta 2 work in israel?

I have an iphone 5 running on sprint that is currently running on ios7 beta 2 because i was able to bypass the UDID activation check. I called sprint and they had to factory restore my phone to unlock my phone by erasing all my content and settings. After it erased, i could not reactivate my phone under ios7 after i got a message saying activation error, your not a developer and your phone could not be activated. I downgraded back to ios 6.1.4 and i was able to activate my phone and the guy at sprint international support told me that the unlock was successful. I then upgraded back to ios 7 beta 2 with no problems and restored all my data. I'm worried now that the pre-paid sim card running on orange-israel that i bought for when i travel to israel in about a week won't be able to activate on the iphone and will give me an activation error like what happened recently when i factory restored my phone running iOS 7 to unlock the phone. Does anyone know if this will be a problem, have had problems like this or are in the same position as me?
