I drove up to Page from Phoenix today. I had native Sprint until north of Flagstaff, where I first roamed on Verizon (SID 1026) and then as I got closer to Page, I went over to Alltel, which is what I am on up here (no Sprint in these parts). What I find odd is that the Alltel SID up here is 53, which is the same SID as down in Phoenix. Yet Alltel has a SID for Coconino County (1025). I am not sure if the 1025 is inaccurate or if my phone is giving an odd reading or if there is some other reason the Phoenix SID is being used up here...maybe it covers a lot more land than do other carriers' SID for the Phoenix area? Anyway, Alltel is great up here. They even have EVDO service, which surprised me. Sprint still hasn't put EVDO in Flagstaff (former affiliate market) yet, but Alltel has it up here. Good for them. Tomorrow I am heading up (by plane) to Bullfrog Marina in Utah...I have no clue if anything will work up there or not. P.S., my GoPhone from ATT no worky up here. I am not sure who the GSM carrier is up here? Dobson/CellOne? I thought ATT bought them though?
