Using an un-activated SIM to test signal strength

I guess the title pretty much explains it.  I was considering switching over to Cricket and was curious if I can stick an un-activated SIM in my phone and still pick up the signal to test the strength?

Just go to Sensorly.com and select AT&T 4G LTE. That will show you how good Cricket is.

Will do.

  Depends on where you live apparently.  Very little info showing in my town, only on a few main roads, though I get good service throughout the county.

  If the phone is unlocked (or on AT&T) I would think it would, based on my sample size of 1.  Just plugged an old unactivated TMo SIM in my phone and it shows TMo as the provider plus the signal strength.  I'm currently with Consumer Cellular on an unlocked AT&T LG G3 FWIW.

Agreed. Very little info shows for me, so I'm gonna grab a few cheap SIMs and see what happens.

  Well download the APP and contribute!

Well, I went and bought a Cricket SIM from Best Buy to test out the signal, but since I bought it from them, does that mean it became activated? Either way, when I put the SIM in my phone, the signal showed up in my phone just without the LTE on the top.

You can get free nano SIM cards for most providers at an Apple Store. Just walk and ask for one. The area maps might show you what's good for coverage, however, you won't necessarily know about signal penetration.

In my place, I barely get 2 Verizon LTE bars (used to be much better), but when I tried a Sprint SIM (used with RingPlus), I only get 3G. If I go outside, Verizon goes to 3 bars, and Sprint goes to 4 bars.
