View originalI would use the old SIM unless it doesn't fit in the new device. Keep the new SIM to use if the old SIM ever needs to be replaced.
Use the old SIM, save the new one to use as a spare. This is particularly handy if you travel overseas, because if your phone is lost or stolen, T-Mobile won't ship you a replacement SIM overseas.
Could both be active with the same number?
T-Mobile (US) does not provide for having two SIMs with the same number. At one time T-Mobile (DE) sold this service under the brand "Zwilling" (Twin).
