| How can you have that many mobile radios in a small space without interference issues?? |

| CDMA is magic. They're not all going to be transmitting at the same time either. |

| ▲ | rootsudo 3 days ago | parent [-] | | This is not CDMA, CDMA is dead it is GSM and most of it will be passive channel and sms is empty bandwidth for the carrier anyway… | | |
| ▲ | toast0 3 days ago | parent | next [-] | | GSM is dead too. It's LTE (or maybe 5G) or it's not online in NYC... | |
| ▲ | numpad0 3 days ago | parent | prev [-] | | GP is referring to CDMA the technology, not CDMA as colloquial term for Qualcomm proprietary cdmaOne/cdma2000 implementations. |

| The use case is fraud. You need thousands of burner SIMs to send millions of spam texts. But the way it works, every SIM needs a radio (the negotiation with the network is very heavyweight compared to an SMS transmission, you wouldn't want to bounce between them by constantly reconnecting). So you need thousands of radios. |

| ▲ | costco 3 days ago | parent [-] | | I've read that at least for for GSM VoIP gateway setups, people typically rotate SIMs because it looks suspicious for one customer to be making calls all day. In fact there is a whole industry most people have no idea about dedicated to detecting these so-called grey routes. Having perused some of these offerings, it seems fairly typical to offer 16-32 radios and 256 SIM card slots. For residential proxy setups, I've seen a bunch of 16 port USB hubs with Huawei LTE modems. |
