I’ve already read a couple of posts about making sure to include dual-SIM capability in the Librem 5; and I agree that this is a worthy and important goal. This is important for three principle reasons. The first is that VOIP (TCP or UDP, but especially UDP) is finicky about good signal strenth. I usually need three bars to use a VOIP app on my Android phone, even though I’m only using about 16KB total bandwidth, during a call. The second reason, and I know many have experienced this, is having data left; but being out of airtime for voice calls. The third reason is of-course security. Personally, I don’t ever want to have to make a voice call “in-the-clear.” Come-on, I mean Edward Snowden. Besides, that’s why we’re all here. But wait; it can get better, a WHOLE LOT BETTER! What if we were to take the dual-SIM Librem 5 and add three more SIMs, for a total of 5 SIMs? You read correctly, 5 SIMs!!! That’s what adding the following gadget can do. May I enthusiastically introduce the SIMORE Triple SIM adapter. Signal strength problems be gone!
