Sorry for digging the old thread, just to update some infos
Well if anyone wish to use Prepaid Broadband on SGP, currently the best one is M1 prepaid broadband if you need unlimited quota(18dollar for 5 days, no daily quota and BT throttling bulls**t), max achivable speed is 7.2mbps if you on HSPA+ network, recommended modem for their broadband are E5331 or E5151, it may not work on 4G modem unless you force it on 3G mode.
Their Prepaid Card aint bad either, first 4G prepaid mobile on Singapore(3GB for 50 days, for 30 dollar).

Singtel prepaid do not offer unlimted quota anymore, thier prepaid broadband are much more expensive, which i dont see any point of this plan, 35dollar for 14GB, vs M1 28dollar unlimited, same speed

It's outdated i think, here is the up to date version https://info.singtel.com/personal/phones-pl...-laptops--ipads
i tried their prepaid card with data enabled for a few months, but i mostly stuck on 2mbps because my location got very weak HSPA signal
Their network is the fastest on singapore, they already got LTE Advanced, and DCHSPA, but for those are for post paid user only
not worth to use their prepaid broadband anymore unless they offer atleast DCHSPA for the speed lol.

Here is the screenshot of the DDL max speed on my E5331 mifi. 710KB/s = 6.5Mbps, i still can get near max speed even if the signal is just one bar on E5331, the other modem already switched to HSDPA

Okay guys, the Signtel prepaid Hicard i'm currently using "Suddenly" upgraded to faster speed

was stuck on 2mbps most of the time no matter what router/modem i used, now on my E355 i suddenly get true 7.2mbps speed

They are just upgraded their prepaid mobile from 3G to 4G, not sure if it's the same plan im using, i have not tested on my E3276 yet

DDL speed:

Hi gaise, Latest Singtel prepaid 4G speed test, their customer service officer told me i can use it with 14GB data plan too

3G speed is around 15mbps, i guess it's DC-HSPA. btw i ran 3 speed test, it ate me almost 300MB of data

FYI: if any of you gaise wanna use this 4G prepaid card on phone or modem, remember the APN is hicard, the default APN for Singtel prepaid is "internet" which will cause the data connection fail if your phone or modem is default to 4G network.

They are currently upgrading their 3G network to DC-HSPA, i didn't get 7.2mbps, mostly 3mbps only, probably my area didn't have HSPA/DCHSPA coverage back then
But now their 3G speed is too close to M1's 4G already, that's 15mbps vs 16mbps. M1 are generally slower and speed isnt stable, but their plan is cheapest.

Maxis LTE speed is better than mine, i don't recall M1's LTE speed can reach 30mbps or something.

50mbps is already good enough, their best result are higher, 60mbps iirc.
Tested on my E3276, it's smoking fast when downloading stuff, 60MB of itunes executable can download within a minutes.
And if subscribe to their Prepaid hicard data plan, 25 SGD for 14GB is best back for bucks, 1GB equal to 3.6SGD with LTE speed
Can terminate my M1 LTE data plan already(if i could) lol
