I had the same problem with the app "not available for your country". My phone was bought in Singapore but my original Google account was set up in the US. Here's what I had to do to make it work:
- Log into https://payments.google.com
- Under Payment Methods, make sure your Google Play balance is less than $10. (It gets deactivated when you change country and reactivated when you change back to US)
- Under Payment Methods, delete any credit cards with a US address. Before doing that, I had to change one of my subscriptions under "Subscriptions and services" from my US credit card to my SG credit card.
- Under Settings, change country to Singapore. Set Name and Address to a Singapore address.
On my phone, go to Settings > Applications > Manage Applications and delete data and cache for Google Play Services.
On my phone, go to Settings > Storage > Internal Storage > Cached Data and press OK to clear cached data for all apps.
Relaunch Play Store and Citi Pay was available to install.
dig n dig. New period till Apr 6.
Nice back to my citipay then

Not sure if i got the calculation right.
Can someone advise?
Citipm using citipay
Standard award: 1.2miles
Citipay award: 0.8miles per dollar
Since $10rebate per 1200miles,
Need to spend $600 to get 1200miles.
I.e. 1.67% rebate
Citi Prestige using citipay
Standard award: 1.3miles or 3.25 citi dollars
Citipay award: 0.7milles or 1.75citi dollar
Same %rebate as citipm?!?
Seems correct to me. However, I using Citibank rewards card that gives 10x points, or 4 miles per $1 or 2.77% rebate (3600 pts for $10 rebate).
Anyway, I value my miles at $0.01 per mile, so to exchange 1200 miles for $10, I won't go for the rebate.
only citipay can get pointscitipay better den andriodpay or applepay?
btw where u get the this from can share link?I am also puzzled by it but from the terms and conditions is possible:
7 . There is no limit to the number of Prizes that a Cardmember can win during the Promotion. A Cardmember that has won a Prize in an earlier 7‐day period will still be eligible to win a Prize in a subsequent 7‐day period.
OK so far. Mainly just use my reward cardLol, for those who have used citi pay for a while, is it having a high reliability? Since my usage within these few days, starting all failed, then I got it working, then now cannot again.
whats invite silver about?
i tot now only got invites gold and invites members?
