Seeing you implying that CDMA is somehow more resistant than GSM means you know very little how cell networks work. The telephony layer for both is SS7.
- wealthyyy 6y agoThe Banks already has anti fraud detection systems in place to detect Roaming attacks. They can see whether number is Roaming enabled or not. The Telecoms do prevent it with Firewalls. As for CDMA, Please see, https://www.wyden.senate.gov/imo/media/doc/Verizon%20SS7%20Letter.pdf https://www.wyden.senate.gov/imo/media/doc/Verizon%20SS7%20L...
- baybal2 6y agoBanks cannot see if a number is in roaming or not, unless the phone company explicitly tells them through some means. I so far never heard of anything like this.
- wealthyyy 6y agoHow come you forget about HLR? Banks can see. There are lot of APIs on the web that provides this capability. One example, https://www.messagebird.com/lookup/ https://www.messagebird.com/lookup/
- baybal2 6y agoThat looks more interesting. Never heard of such APIs being sold for more than a single operator. How many operators in the world sell them this access?
