The total solar eclipse will pass over Bloomington on April 8, and with it, a busy day of tourism and festivities is expected.

But as the big event nears, how will cell service be affected? Can we expect to make reliable calls to emergency services during totality? Will maps and navigation services work? Will messaging and data be slow?

Since total solar eclipses are rare events (only one has occurred in the U.S. since cell phones were invented), it’s hard to answer these questions definitively. But with what we know about cell service in crowds, the advice of experts and emergency planners, and a bit of science, we can start to get a picture of what to expect when totality hits next month.

Will I be able to make phone calls during the eclipse?

The short answer is, probably, yes.

The longer answer is, yes, but you should consider if you need to.
