Skype was very useful to call toll free numbers in the US. For reasons unknown Citi refuses to let you talk to them by email, they will send you statements and other notices by email. Skype to the rescue, free calls to toll free numbers from abroad. That ended with the move to MS Teams Free.
The reason I upgraded the MacOS was to be able to use MS Teams Free. How many hours did I waste on Mission Impossible?
You can’t call US toll free numbers using foreign phone numbers on cells or landlines. Call the regular number that has a proper area code and you’ll be fine.

I know this is 3 months old, but I don’t see the correct answer in any of the comments.
The number given (00-800-8693-5577) is a valid “Universal International Freephone Number” (UIFN).Notice the “00” at the beginning, and no “1”. That’s because the country code is “800”, which is assigned by the ITU to the UIFN service. To call a UIFN, you dial the International Access Prefix, which is “00” in most of the world, except that in North America, it is “011”, followed by 800 and then the 8-digit UIFN assigned.
It is not a U.S. Number, but it is a number for the U.S. company, Wells Fargo. Wells Fargo’s US 800 number is similar: 800-869-3557.
US tollfree numbers are in the usual North American fixed 10 digit format: 8YY NXX XXXX, where 8YY can be 800, 833, 844, 855, 866, 877, or 888 (more reserved for future use).I just called the Wells Fargo number from a German carrier, and the call went through.
It would work from the UK if you called if from a provider which supports it. It would appear that the Mobile Operator providing your UK sim card does not support calling UIFNs, or that it mishandled this call.Another example is Marriott. Their UIFN is +800 1927 1927.
Or the Suicide Prevention and Veterans Crisis Line +800 1273 8255 (this goes to the “988” service in the USA, the same as the US number 800-273-8255).When a company subscribes to the UIFN service, they indicate to their international carrier how they wish the call handled from each country. Any UIFN must be reachable from at least two countries, and can be reachable from any of the 50 or so countries where UIFN service is available. It can be routed differently for each country, thus Marriott routes calls to their UIFN to a call center with agents able to speak the language of the country from which the call is placed.
Citi does not have a “Universal International Freephone Number” (UIFN).
