Hoi Folks,
Didn't forget about you just tied up.
OK Dash Jones, I am not aware of a "global" cell service provider, nor will we create one here, I understand that you think there should be one, there ought to be one, but there is not one, not yet. In the meantime the solutions are, go sat, buy a device everywhere you go, you will get voice on that network, anything else would be bonus, some may offer some type of data service, which would no doubt be hackable to get a full data service, upto the limits of the device, might be the way to go, but this thread will not be able to provide any help with hacking a data connection, and the last option would be to study the carriers in the areas you are going, the list provided in the AT&T link posted above does give info for the national and regional carriers of GSM type service, now that N75 is a tri-band* GSM device as well as WCDMA, (I will try to find a good international carrier list ASAP) maybe not all for everyone, but at least region and company name is provided, in many cases coverage maps are provided. You must interact with your home area provider, for info re: international voice features Customer Care, or Tier 1 support agents, your carrier may have an international customer care dept. ask tier 1 if such a department exists and if they are for provisioning, cust support or both. If they have an international support dept. get a toll free phone # you can call while abroad, and see if they have a free number for dialing from your cell.
When calling for troubleshooting it is very important to call from a land line phone, if possible, but at least another phone, or be near a phone the support rep can call. Ensure you have at least 40% battery power, full would be best, on any device involved, laptop, cell, pda, aircard, etc... Have something to write with, if you get a rep that knows what they are doing, note what they are telling you; you should record all interactions with any service provider, who you were talking to, when, and what was it about, what was done, if call was interupted and you have to pick up again at another time. Yes, it does sond like a great deal of work, and it is, but if being able to connect is important then with cell phone technology this is what has to be done.
I do not need to know your results but post what you have done wrt gathering info about your current service, what you need to add, and support contact info, for the support departments you require prior to departure, during your travels, and when you return to your home area. If your carrier does not have the international support you require, you will have the knowledge needed to find another service provider.
* Hoi Draco,
sorry I am tacking my reply on this post but it is related. Currently AT&T's GSM network, the former Cingular network runs 850 MHz. (The Nokia Dash Jones linked to first covered everything but it would seem.) This network is a 3G GPRS/EDGE/UMTS/HSDPA network. I am unable to confirm at this time any specs of a 4G network. I remember the Samsung 4G device announcement, but have not heard anything WRT 4G network support.
VPN networking tethering a Treo 760 eh? hehe cool. I have helped set up a few but most of my VPN calls start and end with, can you send the security certificates my device keeps asking for everytime I....
I went to the Verizon site but could not load the support pages, found the Treo 700 in the catalogue, and on the
http://www.palm.com/us/support/ site. What OS does it run WM5 or WM6?
I see it is EV-DO. This is what I have on network speeds:
Circuit Switched Data (CSD) found in Timed Digital Multiple AccessTDMA and early GSM networks
TDMA/GSM
9.6/14.4 kbs
Global Packet Radio Service (GPRS) Packet switched
GSM
30-40 kbs
EDGE An extension of GPRS, (iPhone, and Blackberry are the most well known EDGE devices)
GPRS/EDGE
60-170 kbsec
Universal Mobile Telecommunications System (UMTS) Start of 3G tech for GSM.
220-320 kbs
HighSpeed Downlink Packet Access (HSDPA)
400-700 kb
Coded Digital Multiple Access, I would have to check that, (CDMA)
56-135 kbs
CDMA EVDO
300-500 kbs
I think, my direction in this thread will change to providing support links and such in the stead of trying to address specific issues, too time consuming without network tools, and a complete starters guide to the technology. As well, just knowing when a patch or where a new product is available from the manufacture, can save a great deal of grief. As folks post I will try to find useful links, and if anything sounds like something I have encountered before I will pass on what info I can.
It may take a few calls to your carrier's support before you encounter a willing and experienced agent, be ready when you get them, that could be my best advice.
Take care
