Solved the problem with a Nokia 8110 4G, which works great as Internet tether for my thinkpad too (now writing using them in fact). Browsing is near impossible as is using every other internet service, just calls and receiving SMSs from the bank from time to time, which is exactly what I need. They're slowly pushing the use of apps for authentication, but I still keep the (paid) option to stay with SMSs. The phone works great although the UI is a bit sluggish; battery life is not great but enough for use with tethering and calls (no problems whatsoever doing both at the same time). Camera is sub par just like every dumb phone out there; I use it only to make photos of products I need to remember, I never expected I could use it to shoot beautiful sunsets. Price may change significantly, I was lucky enough to purchase it new at €49 delivered, but I've seen its price dancing up to over 200€, which is ridiculous. If you can find it at a reasonable price, it's a nice little device that does the 3 things a dumb phone should do today.
