reception issue

[gapboy]

please hear me out. I was in overseas for a month, where the connection was poor over there using the local sim card. Often the signal will drop to zero bar, and i had to switch to airplane mode and then off it in order to have connection, around 3 times per night.

After returning to Singapore, i encountered the same issue, but only in my home (i don't have a wifi router at home, only using lan cable purely for my desktop and mobile data for phone). I thought it was what i did in overseas that screwed up my phone. But within the 2 weeks, i changed a sim card (starhub -> eight) and also changed a new phone, but the issue still persist, and gets very frequent, and sometimes the after the airplane mode reset, my connectivity only last 1 minute, sometimes 1hour.

Any experts know whats the issue?

Update: called my friend over who uses the same telco, only mine still having connection issues. Also its not just specifically in my house, even at my carpark and 100m away from my house when i tried to buy from the orange juice vending machine.

He said the only possibility he could think of was some virus transfer from my previous phone to new phone, that was why even after changing telco/sim card and changing phone the problem still persist.

Really still cannot make any sense of this.

Wipe the phone and don't do a restore (sounds like iphone)? See if it works

Is this the same as factory reset?

Yup iphone

Looks like two issues added together.
1) iPhone 5G/4G reception is reported to be worse in general
2) Starhub/Eight coverage is not good in your area.

Just get Singtel MVNO (eg: Zero 1 or VIVIFI or CMLink, Zym has no eSIM) to try out. If no good, can still try M1 Maxx.

You can use the eSIM option to carry fast try. No good then port out.

Another wild guess: may be totally wrong.

Your iPhone is a telco version from your visiting country (US?) which may lack certain bands to work properly in Singapore.

Plausible but unlikely, esp in the context of iphone, as iphone in general have very good band support and north American iphone do support a good range of bands including those used in SG.

But until we have the specific model it is difficult to know for sure.

What is the specific model of iphone you use ? Both new and old. Are they SG set or foreign set? If foreign set which country ?

You say it works fine outside the area near your house ?

iphone x and iphone 17 pro

Initially i thought only within my house, but later realised even at my carpark and opposite my house up to 100m.

But not anywhere beyond that ?

Your friend is using iphone or something else ?

What xiaofan say about band coverage is possible, but without knowing whether is local set, not possible to check.

If other place works fine normally unlikely to be phone issue.

Sg apple shop definitely local set.
Are you on 5g or 4g when it works ?

Yup iphone

iphone is a sucker for signal reception.

STM on iphone 14 pro max , 15 pro max, 16 pro max, 17 pro max = 1-2 bars (mostly 1 bar at times)

same place, same sim card, STM on xiaomi 15T Pro, samsung Fold 7, oppo Find N5, oppo Find X9 pro = Full bars.
