Also is the "working" and 2 "non-working" phones displaying VOLTE? This VOLTE is required to "turn ON" for certain phones in order to call/text using the sim that need VOLTE.
For example, SIMBA aka TPG in sg need VOLTE turn on in order to call/text. Phones without VOLTE "turn ON" or have the feature by default will need to download telco apps in order to use VOLTE service to make call/text. 
ps.
Additional infos. Hope the info can be useful to bros going to batam. |
I've 3 phones using 4 different local SIM cards, Samsung S10 is the only phone which i use TPG SIM card and with TPG voice installed. My other 2 phones Samsung A12 and A22 are newer than S10, should also support VOIP which i use Zero 1, Singtel & Circlecare, however both A12 and A22 can't work with Smartfren SIM card. Even my TPG card ($10 50GB plan) also can't connect to internet at Batam. Fortunately i'm in hotel room most of the time which can access to free WiFi.
