Hello, created an account to enquire if anyone suffers from the same experience as I did for the past few months:
Currently on SingTel SIM ONLY+ 45 for the past 8 months
Using iPhone 15 PM
I frequently experience sudden 5G signal loss in MRT tunnels, particularly on the East-West Line (EWL) stretch between Outram Park and Lavender, and on the Circle Line (CCL). It seems Singtel may have recently activated their 5G service on the CCL, as I've been receiving 5G signals there lately. However, the most significant issue occurs on the EWL underground stretch from Outram Park to Lavender, where I experience a sudden loss of 5G NSA. Despite trying to toggle between 5G SA, 5G On, and 5G Auto, the signal often drops to 3G or, worse, no service at all. This is concerning, especially if Singtel discontinues their 3G service, as it would result in no connectivity. Interestingly, when I use my $8 eight service, I still receive 4G signals, which is surprising given that I pay over $30 for Singtel's "premium SIM-only service", yet my MVNO service performs better. I have communicated my concerns to Singtel via WhatsApp, and this was their response:
"SingTel is working with SMRT and the other mobile operators to enhance the coverage in MRT tunnels and stations. The mobile infrastructure in tunnels and stations is SHARED AMONGST THE OPERATORS."
If it is shared, then why is my $8 MVNO service getting at least 4G signals while my MNO "Premium" SIM Only service is getting 3G or no service? Might as well jump to GOMO, at least we are paying lesser for the quality of service we should expect?
Hoping to get some thoughts from likeminded people on this forum and whether there are any better alternatives.
