With one important criteria:
TS preferably be as close as possible to a YES tower.
And the phone is modern enough to support the weird "Outdoor only" Band 38 & Band 40.

Why I emphasise the word "Outdoor Only" , cause it only works fine outdoor.

Unfortunately it was nonsense for me. I was an ex-YES User. Indoor was very weak at home. Some malls cant even get signal indoor. Luckily it was a secondary SIM, but in the end I ported out.

Compared to other telcos, such as Maxis, which has low freq Band 8 to improve Indoor reception.
even Unifi Mobile has Band 5 850mhz. Whereas YES only have very high Bands. Not even something below 2100Mhz. Thats a fact.

Some telcos even have Indoor Boosters inside offices and malls but not for YES.
thats why they had to scam school authorities to install their towers at school ground
So therefore, lucky for you. Maybe the tower is very near to you.
