Here in New Zealand, two of our major mobile carriers use Huawei gear. One uses Huawei for the entire mobile network (from UMTS/LTE base stations to the core network) while another is migrating from Alactel-Lucent (which mostly powers their legacy 3G gear and I suspect their core network still) to Huawei (their entire 4G network as well as 3G at some of the new base station sites). The latter carrier apparently pitted Alactel-Lucent and Huawei 4G gear at a difficult rural test site to decide whether they'd go with AL (whose UMTS/3G gear had been fairly unreliable) or try their luck with Huawei. I presume Huawei must have beat out Alactel-Lucent to win the contract to deploy 4G—a decision that has proved to be successful so far. One major landline telco uses Huawei gear. Many RSPs (ISPs) deploy Huawei DSL/Fibre CPE routers—with some getting good reviews for Gigabit Fibre (which many other branded routers struggle with). Many cheap phones sold by the various mobile carriers (either own-brand or Huawei brand) is Huawei.

While I can understand the distrust for Huawei, I can't deny they have done well when given the opportunity to do so. Alactel-Lucent (an US/EU company) in particular dropped the ball when one of our major telco had a major outage and it turned out they had a maintenance contract (so was AL themselves, not the telco responsible for maintenance of the network). Still took Alactel-Lucent's own experts a full week to restore telco services to a big chuck of our country. Severely dented our telcos' trust in US companies and thus encouraged the telcos to try Huawei instead. So far no major outages attributed to Huawai incompetence which has been a good plus so far.
