People say mobikwik is good but I always get an error completing KYC.
As I said UPI lite is an option but if you need higher limits then you can try Amazon Pay that I have been using for very long time but only for making online purchases not UPI payments but whenever I tried it worked fine but it has its limitations since its considered as bank not wallet you can add upto 10K per month.
If you need higher limits then banks are the only choice, IDFC, Kotak and many private banks offering instant account opening after submission of KYC but the minimum balance you need to maintain will be 10K.
UPI lite is good but the limit makes it not so useful. Amazon Pay doesn't work with many merchants as the ones near me use gpay or bhim. The banks require me to open a savings account after a year using their digital savings account.
Irrespective of whatever merchants use, you scan qr with amazon pay and will be able to make payment, no?
Use https://jupiter.money/, you can do kyc from home, I have been using it since last couple years, it's top notch app. No minimum balance requirement, but if you do maintain — there are benefits.
