Suica App user reviews are relentlessly bad, rip after rip of ‘this software sucks’. Never a good thing to say. Here’s the thing however, when you dig into the reviews most of them have little to do Suica App. It’s also really weird that many reviewers/users seem to think they need Suica App for using Suica at the transit gate. They don’t.
Why are people even using Suica App anyway? You don’t need it to add Suica to iPhone, you don’t need it to recharge Suica. All these things can be done in Wallet app. And now that people are working remotely, there is much less demand for purchasing commuter passes, the biggest reason for using Suica App in the first place. But there is one good reason for using Suica App: setting up Auto-Charge. Set that and you’ll never have to use Suica App.
There’s an important difference to know about Auto-Charge vs. regular recharge in Suica app and Wallet app: auto-charge is locally processed via the transit gate Suica NFC reader. It’s instantaneous and doesn’t care about your iPhone network connection.
Wallet and Suica app recharge are processed via the iPhone (or Apple Watch) network connection. Apple Pay talks with iCloud and Mobile Suica, the transaction is processed online and relayed back to Apple Pay, the recharge amount is added to Suica card. Many network hoops.
There is a message the Mobile Suica twitter account puts out regularly: make sure your smartphone has a robust network connection and don’t use free WiFi when recharging Suica or using Suica App. A bad WiFi connection fools Suica App users into thinking their iPhone is connected to the internet when it is not. This is a particular problem with carrier Wi-Fi SIM auto-connect that bypasses a solid 4G/5G connection and automatically connects to an extremely unstable or overloaded carrier WiFi instead. WiFi on trains and in stations is never reliable and should be turned off when using recharging Suica in Wallet or using Suica App.
Which brings us to an interesting Suica App user review titled “It’s a real urban legend” which explains all the crap talk about Mobile Suica boils down to people trying to recharge at rush hour in transit gate areas with a crapped out carrier or free WiFi connection…the perfect Suica App killer situation. The reviewer recommends “recharge in a calm place at calm time,” to which I heartily agree. Or better yet, ditch network recharge altogether and use Suica NFC Auto-Charge. It will never fail you.
