I recently ported my line from Circles.life to Zero1, and along the way stumbled onto a promo mechanic clever enough that it genuinely tipped me over into switching. This post covers both: the actual porting experience, and why the promo itself is worth understanding properly before you sign up for any Zero1 5G plan.
Quick summary: I signed up for Zero1’s Streamo Bold (4G) plan at $10.10/month, which comes with permanent 5G+ enabled because I ported in from a non-Singtel provider. The sign-up itself was smooth; the only real friction was mail delivery timing, which is more a postal issue than a Zero1 one.
Why Zero1 in the First Place: It’s on Singtel’s Network
Before getting into the promo mechanics, worth explaining why I was looking at Zero1 at all. Zero1 is an MVNO running on Singtel’s network — the same underlying infrastructure as Gomo, ZYM, and Vivifi, three other MVNOs I’ve covered in my best value mobile plan roundup.
Network coverage has consistently been my top priority when picking a mobile plan, ahead of price. My experience with Singtel’s network, through Gomo specifically, has been the most consistently reliable wherever I go — I go into this in more detail in that roundup, including a rough patch I had with a non-Singtel network provider that eventually pushed me to switch. That track record is a big part of why Zero1 was even on my radar as a serious option, rather than just chasing the cheapest plan available regardless of network.
The Promo That Caught My Eye
Zero1 is currently running a “Stay 3 Months, Enjoy the Next 3 Months FREE” promotion for non-Singtel port-ins, valid until 31 August 2026. I signed up for their Streamo Bold (4G) plan at $10.10/month, which comes with:
- 600GB local data monthly
- 5G+ Enabled*
- 30GB roaming to 198 worldwide destinations (365 days)
- 15GB roaming Asia Pacific monthly
- 600GB roaming to Malaysia, Indonesia & Thailand (365 days)
- 300 mins IDD (V019) monthly
- 300 mins local outgoing talktime monthly
- 100 SMS local outgoing monthly
- Unlimited incoming calls & SMS, with free Caller ID
That asterisk next to “5G+ Enabled” is doing a lot of work, and it’s the whole reason this post exists.
