I don't know of anyone that uses 2 different phone numbers, at least not reputable girls. I am not sure what her reasoning would be but I would have the red flag out.

Goggle the numbers. Check the reviews and make sure it is reviews by reviewers who have many reviews. There may be an odd explanation that "may" make sense.  

Overall, I doubt it though.

- Recently changed numbers; one is no longer in service, the new one is.
- Has a personal number and a booker with a separate number.
- Works with one or more agencies in some cities and lists the agency number and her personal number.
- Years ago, people used different numbers on different ads to try to figure out which ad was generating the best ROI. When Tel No 1 generates more profits than Tel No 2, drop the ad with Tel No 2 but keep both numbers.  
- A mistake: meant to give you her google voice number but gave you her actual phone by mistake.

If it was me, I'd ask her why I got two numbers, perhaps less bluntly, with "Should I use #1 or #2?"

Try 6!   That's how many numbers one gal I see has had in just the last year.   She has her reasons, but each time I see her I'm always re-editing my phone listings for her to be sure I call or text to the correct number for that particular session.

Other than that, she's a fine gal.

I am new to the US and using TER but can give you another reason.

 
Mobile providers in Asia are much different than in the US. As are the phones we use. To my knowledge Iphone is still the only exception but in Asia almost all phones are available in single and for an upgrade dual SIM configuration. Here you have huge mobile wars that make it not so much a problem. Both pricing of data and voice along with actual speed of coverage is a big problem in Asia.  

 
In Asia phones are unlocked, and most sales of the phone have nothing to do with the cell coverage. If we change from country to country or sometimes from city to city we can change the cell coverage to meet whats best for us depending on the coverage rates. Simply take a SIM out and put a new SIM in. Very cheap. In Manila and Hong Kong I use a dual SIM phone. One SIM just for voice, one SIM just for Data. Often both SIMS are different carriers and much different rates. Data is much more important than regular voice as it provides full coverage on Viber and Whatsapp.  

 
Here in the US the rates and good coverage are so attractive its not needed for the above, so it most likely has nothing to do with what you see in the profile of the person you are thinking of. However with all of the encryption on Viber and Whatsapp, I think in the future you will see more companions using those apps in the US.  

 
Probably has nothing to do with what your seeing, but it is simply another reason someone could have two numbers.

I saw one a while back who changed her number all the time.  She just didn't want to be on the same phone number too long before she picked up a new one.  While it was annoying for me when I wanted to book another appointment every few months, I kinda dug the security of it all.  

As a newbie, you should see well reviewed providers. If she is, I wouldn't give the multiple phone numbers a second thought.  
If it's a no review lady off BP, multiple numbers could be a red flag.
