Want to test out a MVNO, can I still get text messages from old number?

[sprtfan]

I'm on Verizon and I never thought about using a MVNO until recently. I wanted to test out a few to see if they'd work for me but don't want to cancel my Verizon account yet or move my number until I decide what I want to do. Is there anyway I can access/forward my text messages to my Verizon phone while I'm testing out a MVNO? I can see my text messages in categories section on Outlook.com but I can't access them from my phone mail. I think this might have been something that could have been done using Google Voice before they killed all of the 3rd party apps. I may need to just carry two phones with me while I test things out but was hoping to avoid that if possible. Thanks
