I continue to be impressed with the Nokia E73 Mode. I especially like the form factor, keyboard and quality construction.<\/p>\n
The E73 is a variant of the E72 made for and branded by T-Mobile USA. It comes with support for the operator’s unusual 1700\/2100 3G frequencies and also has a rather nice feature which T-Mobile calls “WiFi Calling” or\u00a0 “Unlicensed Mobile Access<\/em>” (UMA) which\u00a0 lets you\u00a0 make and receive calls and texts using WiFi.\u00a0 UMA is not the same as SIP or VOIP, calls and messages made with UMA are charged against your included plan minutes, text bundle\u00a0 or prepaid balance. Where UMA is most useful is in keeping you connected connected when you are in an area with poor or no cellular service.<\/p>\n While UMA is a good thing it does require some extra setup steps if you want to be able to use WiFi data for browsing and with data aware apps. The setup is not complicated but it does not seem to be very well documented and the out of the phone’s out of box default settings\u00a0 are not optimal.<\/p>\n I initially ran into several issues trying to use WiFi data on the E73:<\/p>\n It took a couple of days but I was eventually able to find solutions or work arounds to most of these issues.<\/p>\n Getting rid of the “\ufeff\ufeffJ007 Error, “Incorrect Security Certificate” was easy<\/strong>.\u00a0 All I had to do was upgrade to the latest latest firmware<\/strong> (currently 0.43.001).<\/p>\n Getting the E73 to automatically switch to WiFi for data should also have been easy thanks to Symbian 3rd Ed, FP2’s new “Destinations” feature<\/strong>. A Destination is a group on cellular and WiFi access points arranged by priority order. When the browser or another app attempts to connect it goes through the access points of the default Destination in priority order until it finds one that is active. On most 3rd ed, FP2 phones there is a default “Internet<\/em>” destination that initially contains your\u00a0 only operator’s packet data access point. When you connect to a WiFi HotSpot, the phone automatically adds that access point to the Internet destination and sets its priority higher than the operator access point. That way the phone will use WiFi if a previously used hotspot is available and fall back to operator data if it isn’t.<\/p>\n But the E73 oesn’t work that way.\u00a0 The Internet destination contains the T-Mobile packet data access point as expected, but WiFi access points get automatically added to a “GAN” destination.\u00a0 GAN (Generic Access Network)\u00a0 is synonymous\u00a0 for UMA. Because the WiFi and operator access points are in different destinations apps can’t switch automatically between them.<\/p>\n Fixing that was a little tricky .\u00a0 The first thing I tried was adding my frequently used WiFi access points to the Internet destination.\u00a0 That seemed to work at first but as soon as I moved out of range of WiFi\u00a0 the phone became very sluggish.\u00a0 I could make calls but was unable to switch to or kill any running apps.\u00a0 When I did a long press on the Home key I saw a mysterious system process called ShareCommServer<\/em> running that I couldn’t kill either.\u00a0 The only way I could recover was to power cycle the phone. Through trial and error I figured out that if any app tried to make a connection outside of WiFi range the phone would hang.\u00a0 Apparently the apps were trying to use the non existent WiFi connection and the OS was blocking on the connection request!<\/p>\n The solution was to remove all WiFi access points from the Internet destination and\u00a0 add T-Mobile’s packet data access point\u00a0 to the GAN destination.\u00a0 Here are step by step instructions:<\/p>\n With the above settings the browser,\u00a0 Gravity and Java apps will use WIFI if available, operator data otherwise. The Ovi Store doesn’t have any connection settings but seems to always use the operator access point. Opera Mobile isn’t destination aware and will prompt you to pick an access point every time\u00a0 you connect. Nokia Mail will either use opperator data or prompt you to choose an access point every time it connects, depending on its “Access point in use<\/em>” setting<\/p>\n “W006.1 ISP error<\/em>” was the hardest nut to crack<\/strong>. This error occurs when you try to use a public WiFi access point at a cafe, store, university or library that requires you to open a browser and log in or accept terms and conditions.\u00a0 Trying to connect to this type of hotspot using the WiFi widget on the E73’s idle screen will always fail.\u00a0 It looks like the phone is trying to talk to T-Mobile’s UMA server before it allows a connection to be finalized.\u00a0 Fixing this will probably require another firmware upgrade but I was able to find a workaround.<\/p>\n At this point the browser will work with the hotspot cconnection.\u00a0 UMA should also automatically connect allowing other apps using the GAN destination to work.\u00a0 Sometimes UMA doesn’t seem to automatically establish a connection.\u00a0 You can tell UMA is connected by the presence of a\u00a0 pink globe in a circle icon in the upper left corner of the screen (image bottom, right). If UMA doesn’t connect automatically and you want to use it for calling, texting\u00a0 or as a data provider for another app:<\/p>\n If you found this post helpful, have questions or have discovered other E73 connection tricks please leave a comment.<\/p>\n","protected":false},"excerpt":{"rendered":" I continue to be impressed with the Nokia E73 Mode.
