Hi everyone, i manage to link my Sierra 320U with my win10 just now,

but now stuck with Error 633 when trying to connect with MDMA.

i already follow the guide on post 2

im trying to set band 7 as only default since my i150 connection speeding up and then putus

anyone can help me with this problem?

did u close the sieraa dialer manager first ? or check under task manager window 10 make sure nothing is dialing the sierra,..

yes i close the sierra dialer manager and kill the background proses.

i will try again and check if there's something else dialing the sierra

Have u manually create a dialup connection name MDMA before u dial with MDMA?

Yep, my error is from the MDMA dialer as u can see on my screenshot.

already try google around, testing what posibble and what not, all fail

dunno what to do

dayumm was hoping i could with a router all in one for peace of mind,

huawei moden e3267 still king now?

Yes I know its now the year 2020. Whereby everyone is into 4G and now going to 5G.

But anyone here still using 3G (3.5G)?

Recently I gotten abit fedup with 4G (Using Yoodo aka Celcom)
that i decided to take out my abandon Huawei B660 3G router + modem.
I think mine is 3.5G , not HSPA+. Cause its rated max throughput at 7.2MBPS.

Previously was using an old Xiaomi Redmi 2 phone , as a 4G modem and enable Hotspot.
Only advantage of my Huawei modem, is that it has better WIFI reception. I feel the Xiaomi WIFI transceiver is slightly weak.
But I am aware that WIFI signal plays a role.

Problem is my area here , sometimes at night can be slow. But tolerable.
Living in Subang Jaya, so its a city centre.

Already lodge a complain to Yoodo and they acknowledge the tower I am connected has high usage (reported before MCO Lockdown) . Doubt they will do anything about it.

I did a speedtest on my own Samsung hp, switch between 3G and LTE (supposedly have LTE-A / 4G+) , run Speedtest, and the LTE only fare slightly faster.
Tested my wife's DIGI , did the same thing , and find that LTE sometimes a little bit faster.

So I thought why not downgrade to 3G since hardly anyone user is using it.

3G user here because 4G line is dead at my house ground floor. Even 3G is almost dead. I think barely 5% of the ground floor area has 3G signal. Making a phone call is close to impossible in my house.

Woah..yours is really bad. Really bad..
Have you considered porting out to another telco?

If I were to goto my parents home, the 4g signal is kinda weak indoor. But 3G is strong.
So what I do is, I use MTK Engineering app, and force it into LTE mode only. Of course signal bar is only about 1 bar but at least I got 4G.

I tried 3G and yeah it works well too.
Akin like ..4G = Federal Highway, PLUS highway.
and 3G = Kampung road.

I have tried all telco. This place is not that developed. Telco has no plan to build more stations.

Sorry I didnt realize you're from Sarawak. So I now truly understand why you have very bad line even for 3G.
Meanwhile at my mom's place in USJ (Klang Valley area BTW), dammit..maybe that particular road has weak 4G spot.
Heck even when I stand right at the car porch near the gate, still only 1Bar of 4G.
So i have to depend on good ol' 3G. Which is not too bad.

Still able to stream for Zoom and Youtube videos.
