Jelly 2 can work fine in Verizon network. But as it is not certified by Verizon, your Verizon Store may refuse to activate your new SIM card with it. If your old device has a nano sim, just insert the old sim into the Jelly 2. You can also activate a new SIM card with another Verizon certified device and then use it in Jelly 2. I have used a Jelly 2 for about a year now. My local Verizon store was able to activate my first Jelly 2. Six months later tried to activate a second Jelly 2 at the same store. They told me it can't be done. Verizon support confirmed the sim could be remove from current phone and installed in the new Jelly 2. I swapped a sim out of a Galaxy 9 and this second Jelly 2 also works fine on Verizon.
