So, with today's software update, has Rezound become a true global phone, i.e. any SIM can be used?

Just hung up with a woman at Verizon Global. She wasn't a tech, just their front line person, but said she had set up many people to use their Verizon phone overseas. She had heard nothing of the Rezound firmware update. According to her, one can fly overseas, buy a SIM there, give Verizon a call to change some setting, and the usage will have nothing to do with the Verizon global service or rates. Something is fishy about this, I wonder, whether somehow one's usage will roll back to Verizon, resulting in their humongous bill.

Still no cigar. Put in my global SIM, changed the network setting, and connected to AT&T. But nothing really changed: I was able to make and receive calls, receive texts, but not send texts out. So what was "enabled" yesterday with the firmware update?

I had heard the AT&T "bands" were blocked, but the global OTA ROM works with an Straight Talk SIM and other pre-paid GSM SIMs in the US... Just insert the SIM, set the APN information, and toggle the radio mode and it works, although from the few people I have seen who have tried it the radios seem very "weak" compared to other HTC devices when accessing AT&T's network, and speeds are very low on the stock ROM. This can be overcome with a CDMA/GSM ROM like Tron, Infection, Pac-Man, MIUI, or a handful of others that are now stable and extremely usable as daily driver ROMs with much increased performance and battery life, native WiFi tethering, and much more.

Sorry to sound so dense, but what exactly is the APN information and how is it set/reset? I just spoke w/ a guy from VZW Global and, according to him, to use the VZW network overseas just the radio mode needs to be switched to GSM. He said that, otherwise, I'd need to contact the source of my Global SIM for any special instructions.

The VZW guy is talking about using your Verizon phone as a Verizon Global ROAMING phone, which requires you to do nothing, but that isn't really "global"... the phone is unlocked, it has to be (by law, I think), so to use it on another carrier you will need a valid SIM card from that carrier, insert it into the phone and your phone will now be on that network (AT&T or whatever) as soon as you switch the radio mode to GSM or Global... then to use mobile data (and MMS) you need to set the APN information, which is under the GSM setting in Mobile Networks. Each carrier uses their own APN settings, and should provide that too you or a simple Google search will come up with most of them.

To the rest of us, Global Mode means you can use a SIM from another carrier, for example picking up a GSM pre-paid SIM at an airport in London, swapping it out and setting the APN information in the phone, and you get a new local phone number and use and PAY a different carrier (basically an unlocked phone) for service, not Verizon.

For some ideas, look here: Internet Settings / APN Settings / MMS Settings or this app in the Play Store: Offline SIM APN Database
As far as finding out more about the SIM itself and who the carrier maybe, there are any number of apps in the Play Store, just search for "SIM info" or something similar and find the MCC and MCN or SIM Operator code (Usually the MCC+MCN giving you a 5 or 6 digit number) and you can look it up in any of several databases like this one: Number Portability Lookup | Realtime Carrier Lookup | HLR Lookup

Thanks a lot, acejavelin. As to that XDA info, it somehow stuck in my memory that they reported exactly the same issue (inability to send texts) before the last OTA. Hopefully, we'll have some people who take their Rezounds abroad, try them there, and then post their experience. P.S. BTW, I think there used to be another thread or two about this whole issue w/ Rezound, but now I couldn't find them.

I kinda want to hit this hibernating horse one more time. If a plain vanilla global SIM causes the phone to ride on a different network when moving from country to country (say, AT&T in the US, Orange in GB, etc.), does this mean that APN has to be reset accordingly with every new network?

The "global" mode in this phone is very hit and miss though, especially using AT&T in the US, many users including myself are not able to get better than Edge speeds, HSPA just doesn't work.
