cell phones in Ensenada?

Hey, I was wondering if anyone knows if you can use your cell phone in Ensenada without international rates? The Dr.'s info said sometimes you could since they are so close to the border. It also said Cingular is the one they had the most difficulty with. I had Cingular but now it has been bought out by AT&T.......................so I was curious if anyone else has dealt with this. I leave on Monday so the sooner you could respond the better. Thanks

I used my Cingular cell phone in Ensenada... I added for $5.95 a month an international calls from inside Mexico calling plan... it was still pretty steep though but the connection was great. ~Michelle
