Last year in March of 2015, I took a trip to Las Vegas. My cell coverage was marginal at best and my data was basically non-exsistant. I'm planning another trip the End of March 2016 and want to make sure there isn't a repeat of last years lack of service. I use an iPhone 6+ which I hear just updates its self when traveling. Please offer up any suggestions as to how I can use the service I'm paying for. I'm Staying at The Wynn; address 3131 S Las Vegas Blvd, Las Vegas, NV 89109

Thanks.
