Selection between EG25-G or EC25-GL

IoT Modules LTE Standard Module

Hi All,

I have been reading the forum topics and have been picking up valuable info from many sources.

I am migrating from EC25-EU to EG25-XX to enable global coverage for an IoT device but having a difficult time determining if the -G or -GL variant is the better choice to replace the EC25-EU.

I think EG25-G is the better choice due to its field maturity. Is there anythign about the EG25-GL that makes it the better choice that i am missing?

thx!

Hi,

Good question, and your instinct on the -G’s field maturity is fair. But for a design you’re explicitly opening up for global coverage, I’d actually lean toward the EG25-GL. Here’s the reasoning:

RF-wise the two are almost identical (both Cat 4, 150/50 Mbps, same Gen8C Lite GNSS, same WCDMA/GSM bands). The -GL adds just two LTE bands over the -G:

  • LTE-FDD B66 (AWS-3 / B4 extension) part of the global band set and important for full North American carrier coverage. The -G stops at B28 on FDD and does not include B66.
  • LTE-TDD B34 (China/Asia).

The bigger differentiator isn’t RF though it’s certification. The EG25-GL is Quectel’s actively-maintained “single global SKU,” and it carries a much broader, current operator-approval list: Verizon/AT&T/T-Mobile (US), Telus (CA), Telstra (AU), Spark (NZ), plus GCF/PTCRB/FCC/CE/UKCA/IC/Anatel/SRRC/KC/NCC/JATE-TELEC/RCM. If your end device has to run on carriers that require module-level certification North American operators in particular the -GL saves you a certification path the -G may not cover with maintained approvals. For a genuinely global deployment that’s usually the deciding factor.

On migration effort: it’s basically a wash. Both sit in the same unified form factor and are land-pattern compatible with the EC25 series, so the redesign from your EC25-EU is the same either way. One small caveat the -GL is specified as LGA (with LCC-compatible pads), so if you’re reusing an EC25-EU LCC footprint, just confirm the pad geometry against the -GL package drawing. Usually fine, but worth a quick check.

Bottom line: if “global coverage” is a hard requirement, EG25-GL B66 plus the maintained carrier certs are exactly the things that come back to bite you on the -G later. The EG25-G is still a solid, mature choice if your deployment is regionally scoped and you already know the target networks don’t need the extra bands or carrier certifications.

Hope that helps.

Brillant assessment. Thank you! :folded_hands:

Hi,

does Quectel offer EG25-GX (threadx) similar to EC25-EUX ?

Thanks
