Keep in mind that this doesn't need to be a Raspberry Pi and can be any computer. With some networking magic (and potentially network namespaces) you can also run multiple dongles & proxies on the same machine. A bit of hardware engineering will allow you to decouple the SIM card from the modems themselves, so SIMs can be kept at a central location and assigned to modems at will, potentially automatically depending on remaining credit/carrier blocks/rate-limiting/etc.
- pawelkobojek 4y agoYes, RPi is totally optional. This article just provides an example setup.
- getcrunk 4y agoHow would you decouple the sims from the modems? Would it just be about reading some info off the sim and then passing it to the modem?
- monai 4y agoOne of the Osmocom projects[0] does precisely that. [0] https://osmocom.org/projects/osmo-remsim/wiki https://osmocom.org/projects/osmo-remsim/wiki
