I travel to Israel on a regular basis. I got a new sprint iphone5s in October. Previously I had a sprint iphone 4s, and when in Israel, the phone would roam on a GSM network with 3g internet speeds.

The 5s in Israel, will not roam on GSM and only on CDMA 1x. When in GSM mode, it shows no service.

Many calls to Sprint tech support and to the Sprint corporate sales contact say all is fine, which is really not as 1x is much slower than 3g. They claim that they changed roaming partners and only support cdma 1x roaming, but cdma is going away in Israel.

Any one know why sprint canceled roaming agreements with GSM carriers to only support CDMA?

Any way to force the phone to roam on GSM ?

Thanks
