I understand the theory -- I'm just trying to help a guy who seems to need a little help. The "+" is not used very much in the US and many phones don't have the key marked. You have to dig thru the manual to find out that its "hold the 0 down for a long time" or some such. "00" works with Riiing/UM and he was little unclear on that, using just "0"

Yes, perhaps "+" before the phone number and the whole GSM is just a European unpractical invention from the American point of view :D
However, I suppose that + preceded numbers work also in US GSM networks, right?
I'm surprised after all that "+" may not be explicitly placed on the keyboard a GSM phone:). Anyway, now it's clear to me what you advised to dial numbers preceded with "00" instead of "+". And IMHO if "00" format works in UM in Europe, it should work anywhere independently of the local formats. It's because UM itself uses callback - the destination number is transferred as a USSD code to in the number format acceptable by the FL1 network (+ and 00 both are). And the are also USSD non-prefix solutions like in case of Hop: http://www.hopmobile.com/manual4.html.

+ works in the US on gsm networks...remembering also that in the USA and Canada, the international dialing prefix is 011 not 00...but + on gsm networks resolves that....but there is no standardization of how to dial + on various manufacturers nokia does it differently than SE then etc.

That was my point -- you expressed it better then I. The first time somebody told me to press the + key I was confused -- I had 0-9, *, # but no + :help:

I am always of the opinion that all numbers on a GSM phone should be stored with the + sign. Makes life easier when one is travelling internationally. I did exactly that on both of my GSM phone. The manuals that came with the phones even suggested that.

It's also true that the CDMA phones do not understand or even allow the + sign to be included as part of a phone number. My CDMA phone is fairly recent and does not have the + sign on the keypad.

So I stop messing around with my phone. Now I am in Rome. My UM sim card is not working. No Service message. I need to make and receive calls. What do I do? I had given this number out for business and friends. It was working fine in the USA. Nokia, properly unlocked.
Please send your advice and tips quickly.

See if you can manually select a different network. Keep trying. Your phone MAY be stuck on 1900, which does not work in Europe. My old P280 required me to switch to 900/1800 in Europe.

There is always the landline number for customer service or email to them. You seem to have internet access.

I am in the hotel lounge but I am going to be traveling alot. I can use this internet for a couple of days.

I have the Nokia 6800 - it is supposed to work in Europe.
Under connectivity I can chose - infrared-GPRS or synchronization.

Is that anything to do with it?

Don't have the 6800. How about NETWORKS or CALL SETUP? Do you have a manual? I can check to see if I can download one.
