USA: 4G providers for Opis mobiles
Quick start
Find your provider in the table. If it's listed, the 60s mobile 4G and PushMeFon mobile 4G work there.
Why the provider matters
In the US you need a provider that accepts your own phone (BYOD/BYOP). Many only accept certified devices. Ours are certified for the providers below.
Setup
Insert the SIM and switch on. The phone sets itself up. Not working on a listed provider? E-mail support@opis-tech.com with the model, the IMEI (under the phone) and your provider.
Provider compatibility check
Many providers check your IMEI online. "Partial compatibility" is fine: the phones make calls only, no data. The phone may show as OPIS MOBILE, OPIS TECHNOLOGY DEVICE, QUECTEL, QUECTEL EG21-G or OPIS QUECTEL.
Activation code (last resort)
Only if the phone doesn't work. Lift the handset, wait for the dial tone, dial your provider's code exactly. One ring = accepted. Then test a call.
