Is the LG G7 optimized for each network on which it is used?

[inept311]

I am so new to cellular phones that my head is spinning. I am loosing my cushy position sharing my offspring's phone plan.

I would like to try Sprint's 2GB 4G LTE plan on an LG G7 ThinQ.
If I do not like Sprint's service, can I take the phone to Verizon?

I have been told that the phones maybe optimized to operate on the carrier's network from which they were purchased.
If that is true, I have been told that some features on the second carrier may work poorly or not at all.

Sprint offers (?) 14 days refund. I do not know if there is a restocking charge. I do not know if 14 days is long enough to determine if I like the service.

I have priced the Samsung Galaxy S8 & S9. Would these phones fit into the same question as the LG G7?

Thank you all for any information or direction.

Verizon probably won't accept it.

It's true for a few things - the frequencies the phone operates on, the type of system it operates on (but both Sprint and Verizon are CDMA), the voicemail, video calling, Wifi calling.

Sprint offers (?) 14 days refund.

All 4 carriers (AT&T. Sprint, TMonile and Verizon) do (everyone else is a mobile virtual network operator - they use one or more of those carriers).

I do not know if there is a restocking charge.

Ask, but probably not.

I do not know if 14 days is long enough to determine if I like the service.

All you have to determine is whether Sprint has solid signal wherever you need a signal. (And that gets down to inches, so sit at your desk, don't check just in front of the building. [It's not coverage that goes by inches, it's dead spots - if right where you sit is a dead spot, you'll have to move whenever you want to use the phone.])

Question, yes. Phone, no.

If you want a ThinQ, just buy it from the Google Store. That will solve any carrier imposed restrictions and if you activate it on Project Fi they knock off $350 which brings the price down to a reasonable $450.
