Help Service Mode = Blank

[RJB]

Been having trouble with my TMo WiFi calls dropping...

Read online some suggestion that going into "Service Mode" and turning off WiFi would help.

"Service Mode" - from what I've read - is accessed via dialing *#0011#.

It SHOULD give me screens that look like:

and then

Instead, I'm getting a blank screen and no WiFi option:

This is true whether or not my WiFi antenna is turned on, or my Teleco.

I'm overseas, so I'm keeping my 4G antenna off, but I can't see how that would make a difference.

Help/thoughts?

Bump.

Set up a new ADSL service, bought a new modem/router, still Wi-Fi calls drop on TMo Galaxy Note. (2010 Galaxy S did Wi-Fi calls fabulously).
