I have a comms HAT for a Raspberry Pi (bought by my colleague) that only supports 1.8V SIM cards
Then, I was making considerations to purchase an IOT SIM card, to which I haven’t obtained one yet. And now I’ve seen this Hologram Global IOT SIM card.
According to its specifications, its operating characteristics says it supports 1.6V, 3.0V and 5.0V operations.
My question will be: can a module that has a 1.8 volt SIM card slot support a 1.6 volt SIM?
Or another way of asking this: can a 1.6 Volt SIM card run in a module that only supports 1.8 Volt SIMs?
Does a difference of 0.2 Volts matter?
On a side note, is anyone here using Telstra IOT SIM cards? Are they rated at 1.8 Volts?
