    Last couple of days my phone has sporadically been giving me an "invalid sim" error. Usually powering it down and back on will clear it for a while, but once I had to remove and reseat the sim card.

    Is this sounding like a hardware issue, or could it be something with the card?

    Not a lot on Android devices on the subject,but what little I've found is it's typically a WI-FI Calling error of sorts OR an error that pops up if you've unlocked a carrier device & use a SIM Card from a different service provider that does not support WI-FI Calling (Or MAYBE vice-versa,a SIM Card from a WI-FI Calling provider in a phone that may not be able to support it).

    So,at least it doesn't seem to be a hardware (device) issue.
    I'd contact your service provider,especially if it's a carrier-branded phone & the SIM is the same.
    Either way,a call to your service provider is in order & worse-case scenario (hopefully) is starting fresh with a new SIM Card.

    On non-Android devices,a bug with WhatsApp seems to be some what prevalent.
    If you're still coming up empty,the most prevalent Google search seems to involve i-Phones.
    Take your pick of search hits on that,a lot to choose from.

    Please keep us posted on your outcome.

    A replacement sim card didn't help, nor did a factory reset. It's looking like a hardware issue to me. Time to look into a repair. Happy day.
