If I purchase this phone I would find out. but I am not sure of buying it. because I don't know the maximum # of characters per txt msg. to make a 3 way call on the r410 while on a call you press send and dial the 2nd # and then press send once or twice more to join both calls. it may be the same on the r450.
It holds 160 Characters... The only reason I bought it was because of the carrier. Metro Pcs doesn't have a contract, and I heard.. (I dont want to start any rumors...) but I was told by a few of the Metro stores that they will be getting a 3G network sometime in the next coming months.. If that's the case seeing how there are an abundance of excellent phones that can be flashed, I'm considering switching phones when they (Metro PCS) announce the switch. Of course they will charge up the booty for unlimited usage, but it wont be anywhere near the cost if I were to have a contracted carrier.
