Have been looking for dumb phones which could run proper QRscan UPI payment for awhile. Have encountered phones with 123upi and it's skin or just straight up android. I just want a dumb phone for voice calls, sms and proper QRpay UPI. Have heard of JioBharat and more recently Nokia 2660 providing this feature, but from my experience people who own those phones tell me UPI doesn't work on JioBharat yet and that their Nokia isn't showing the supposed update as of yet. So i would really appreciate if i can get any help with this.
