The general problem — too many APPs in my primary phone. Many of them rarely used.
A specific problem — I need to maintain China mobanks for two persons, and I don’t want to “switch user” on (for example) icbc mobank.

The solution — host a number of APPs on a secondary smart phone

• China mobanks for “special” user account that I don’t need on the go.
• Alipay for wife
• Citi.sg
• AXS
• healthhub
• simplyGo
• mayb
• ^^^ done
• PNB digital?
• Singapss? Technically disallowed
• hsbc.cn .. secondary phone too LOW
• ChnM? would need it on primary phone while in China
• starhub? too slow in secondary phone  … confirmed with 1633
• Grab? No
