Is it the authentication SMS for the humble bundle account itself ?
Support should be able to send you SMS manually or something (happened to some users before).
If you are not using authenticator for humble bundle yet, do so as soon as you'll be able to change your account settings. Email authentication is inferior just because you have to wait for response first.
Also instead of authenticator app, for all authenticators use qr scanner app first and save the results. That way you can keep the backup yourself and you don't have to rely on sync and other automated stuff (easy to load into new phone as well).
My preferred QR scanner app for android:
QRbot

Hi everyone.
Could you please tell me where is the data regarding in-app purchases stored? When I reinstall the app I unlocked through the purchase in-app, it usually is already unlocked. Is the data that helps with that stored in the same place as the app data backup, or is it stored separately by the Play Store? If I’ll decide to turn off the app data backup in the settings, will my purchase data for e.g. net.qrbot be restored nevertheless?
QR bot has really nice material design, can read more codes than the other apps I tested and can do lot of other things (history with images and notes, scanning pictures, sharing using QR), but unfortunately it has adds if you are a new user.
MobiGo looks good as well and Barcode scanner from Manatee supports most barcodes, but last time I checked it it had no history and only horizontal scanning.
This one's the best imo.
A redditor made me change my mind, this is the best one. I didn't see any ads or iAPs, it's a false positive
QRBot is the best scanning app there (simple, no ads, material design, can read almost any type of code)
QRbot is the best of the many I've tried, it can even create codes. Lightweight, good UI and fast.
Try QR Bot. Best QR app.
Edit: This is it..
