As many of you know, I am a Sprint customer. Sprint has roaming agreements with both Alaska DigiTel and ACS Wireless. Alaska DigiTel is the still-struggling preferred roaming provider for Sprint. I've never previously used their network in Juneau, but I'm not impressed. It doesn't perform quite as miserably as the one in Fairbanks, but I've experienced numerous issues: - Most of the network is still IS-95. Only one tower supports 1xRTT data--in theory at least. I haven't been able to successfully use this service at all, probably due to capacity issues. - So, on the subject of capacity, it falls woefully short. When three cruise ships arrive in town at once, disgorging thousands of passengers into the streets of Juneau, the network falls over and dies. I've gotten constant "System Busy" messages, and Alaska DigiTel acknowledged the issue, noting long-term plans to address it with their pending EV-DO upgrade. - I'm able to send text messages, but not receive them for some reason. I reported the issue to Sprint and Alaska DigiTel; the latter carrier plans to follow up in an effort to repair the issue. I'll report later as to whether these efforts were successful. - The CDMA1900 network consists of only 7 towers throughout Juneau, Douglas Island and the Mendenhall Valley. This creates very patchy coverage with lots of drop zones. - Worst job in Juneau: Alaska DigiTel representative. The tired rep offered no assistance other than to give gave me the phone number of customer service in Anchorage. With a dismissive sigh, she said "We have issues." ACS is the secondary roaming partner for Sprint, and I've been spending a lot of time on their network due to the above-mentioned Alaska DigiTel issues. Unfortunately, it's not all roses with them etiher... - Coverage, while markedly superior to Alaska DigiTel, does not meet Lower 48 standards. For example, there is no coverage at all inside the Juneau Wal-Mart, and coverage is poor inside Costco. These are both extremely popular shopping destinations in Juneau. - Text messaging does not work at all, either to send or receive. ACS says it's working for their customers and they're supposedly researching why it's not working for me. - EV-DO data is available in Juneau, but it's not showing as available on my handset. No matter, 1xRTT data would be sufficient, but unfortunately it doesn't work either (I receive "registration failure" when I attempt to use it). ACS says it's working for their customers and they're supposedly researching why it's not working for me. ** EDIT: Wow, that was quick! I just got an email from ACS (almost unbelievably, an email from an actual person complete with a direct phone number to reach her). They confirmed that their roaming agreement with Sprint is for voice only, which is why text and data services aren't working. So, if you're a Sprint customer, be prepared for life without data when you're roaming on the ACS network (this is entirely contrary to Sprint's coverage maps). So, as usual, CDMA roaming is a rocky experience for Alaska visitors. The GSM network operated by AT&T (ex Dobson Cellular), meanwhile, has been flawless--apart from slightly less geographical coverage than the ACS CDMA network. Coverage quality is similar to ACS, also not meeting Lower 48 standards.
