Hi - Today I 'upgraded' my HTC Thunderbolt to an iPhone 5s. I used the mobile hotspot previously which worked wonderfully. In addition to the iPhone, I also got this jetpack to connect my devices to share data. The signal strength is not up to par and far worse than my 'old' Thunderbolt's hotspotting capabilities.

Zip code is 60622. Strength is -104 dBm. 2 bars, maybe 3 if I am lucky.

I have removed and re-inserted the SIM card. Without having to throw more money down for a booster or other device, is there anything that I can do to improve the strength?

Help! I just want parity to my previous 'old' phone's capabilities!

Thanks

Ben
