We have RUT240 as a failover device. Our plan is to put a cheap SIM in it; then in emergency when our primary cable internet fails, switch to one of our phone SIMs on which we have large data allowances.
With a prepaid SIM from the provider Three all works fine. I then inserted the SIM from my UK monthly contract mobile, with Vodafone, and it appears to connect, with an IP address, but no data passes through. Same for my wife's SIM on the same type of contract.
Is this a setup problem on the router? There are some rumours that Vodafone are not allowing "phone" SIMs to be used in routers, but Vodafone denied this strongly on a support call.
Status shows as "registered (home); Vodafone UK; 4G". SIM card status "SIM (Ready)". But 100% loss when I ping 18.104.22.168 from the router.
I have tried the following with no success:
- update firmware to 01.13.1
- remove SIM PIN altogether
- change connection type to PPP
- manually enter APN of wap.vodafone.co.uk
- as above and add authentication CHAP or PAP with credentials wap and wap
I have downloaded the troubleshooting file if needed.
