Question: if i put my ATT sim card into a rumor phone will it still work?

i have an ATT plan with a LG View phone. i do not like touch screen and i want a full keyboard. i am wondering if i put my sim card into a rumor 2 if it will work. i can not test myself because i want to make sure it works before i make the purchase of a rumor. thank you in advance for your help.
