Do you get errors related to the SIM card on your iPhone and can't see the cellular signal bars? As a result, you can't make calls, use mobile data, and send or receive texts?

Usually, this happens due to problems with the SIM card you're trying to use. Your iPhone will show error messages like Invalid SIM, No SIM, No SIM Card Installed, SIM Not Valid, SIM Not Supported, and SIM Card Failure.

Other times, the fault may be with your iPhone because of which it's failing to recognize the SIM card. Let's tell you more and show you how to fix SIM card issues on your iPhone or cellular iPad.

Visible now supports cellular Apple Watches for just $5 per month

Around three months ago, I shared my user experience with Visible as a second carrier for my iPhone. Visible, which operates on the Verizon Wireless network, offers outstanding network coverage for as little as $25 per month with unlimited 4G LTE & 5G data, talk, and text, and with unlimited tethering included!

Just this past week, however, Visible did something I never saw coming. They added support for cellular-capable Apple Watches. And much like Visible’s hyper-affordable cellular plan, enjoying cellular connectivity with Visible is just as affordable.

I added Google Fi as a secondary carrier on my iPhone, and this was a great choice

I’ve been a loyal AT&T customer for the better part of a decade now, and while I’ve definitely experimented with other carriers in my area – Sprint and even Verizon – I always found myself happier with the AT&T experience and crawled right back before my old and grandfathered plan lapsed.

However, while AT&T certainly takes the lead for cellular data speeds in my area, coverage is one attribute that it lags behind in, especially in the more rural parts. That’s why I decided to try something new: Google Fi for iPhone.
