Already happens. You can buy jigs on aliexpress that hold 128 SIMs and round-Robin across 8 GSM radios. It’s not all for spam per se. Some countries/providers charge a ton for international incoming calls, so bypassing this by IP and making calls in-provider only saves a lot of $$$ for gray-market connectivity. And it’s cheaper for setting up of in-bound calls too than a business line. https://m.aliexpress.com/item/32947688074.html?spm=a2g0n.productlist.0.0.22360AOg0AOgwe&browser_id=b5137ec38df14d7bafc50f464f461a96&aff_trace_key=6a70a2cbf7ab443391dc04aa8734eac8-1673803666455-00705-UneMJZVf&aff_platform=msite&m_page_id=k8tdhi5wdccawfs5185ff5245236576ed7d1204928&gclid=&pdp_npi=2%40dis%21CAD%21417.56%21338.22%21%21%21%21%21%40210318bb16750258599811368e5aa9%2166250245831%21sea&curPageLogUid=SpA4GUNOFJTK&algo_pvid=a38a28e8-80d9-4192-bdc7-9a48dc7b3313 https://m.aliexpress.com/item/32947688074.html?spm=a2g0n.pro...
