Hello, just joined FT, great forum. First post so hope doing this correctly - - couple questions about MPC app use at SFO. I have read thru all of this thread, and the MPC website FAQ's, can't quite nail down several points - - 1. is there wifi in the SFO arrivals area before getting to the MPC lines, or are there MPC zones available, to submit and get your receipt immediately after deplaning via wifi (I do not have US cell access )? I am coming in from NRT on an NH flight in May. 2. I have seen some FT posts here about the time stamp issue on the receipt, i.e. iPad set to Asian timezone. Does the receipt have hardcoded time issued from the issuing location? Major issue or workable? 3. Assume wise to come in with the paper form ready in case the system is out or problems with the processing, as I've seen in several posts? Thanks for any guidance on this.
