nope
still the same speed before and after 5G
DNB using own fiber backhaul and different b28 n78 spectrum unused by telcos

My 4G (celcom) still same. Not getting any faster or slower.

look at your signal strength
week signal, normally in the middle of between tower coverage
either phone keep changing LTE band or changing tower
this nothing to do with 5G DNB

Mobile 4G/5G Internet has limited bandwidth capacity and high urban subscriber density per cell tower = is often subjected to traffic congestion during peak hours, especially in urban areas, ... unlike Fixed/Immoblie TM Unifi Fiber Internet. Eg each cell tower has to serve a maximum of about 500 active subscribers at any one time whereas each fiber cable has to serve a maximum of only about 50 active subscribers in linked-homes or shops or condos at any one time.

Afaik, DNB1 has a total of 5.6Gbps bandwidth capacity per cell tower for it's 5G bands of 700MHz and 3.5GHz, to be wholesale to the 5 celcos. DNB2 should have about the same 5G bandwidth capacity per cell tower in mid 2024.
....... DNB1's high bandwidth capacity of >10Gbps per small-cell for it's 5G mmWave Band of 28GHz can be ignored because of it's very short range of about 50m, whose small-cells are only deployed in downtown city centers and high foot traffic areas like MRT main stations, shopping malls, stadiums and concert halls.

For 4G, each celco has about 2Gbps of bandwidth capacity per cell tower = totalling about 10Gbps of bandwidth capacity (= 5 celcos) for Bands 800MHz to 2600MHz.

So, from a mobile subscriber's perpective, by mid 2024 when DWN (= DNB1 and DNB2) is in operation, 50% of subscribers should remain on 4G and 50% of them should be on 5G, in order to minimize traffic congestion during peak hours, esp in urban areas. Note that subscribers can opt to use 4G even if they are on a 5G mobile plan.
....... Of course, this scenario is subject to the government not phasing out 4G, which may happen if >80% of subscribers are on 5G in 2025 = often causing traffic congestion during peak hours..
