No calling available in USA

[Ljw7]

I have purchased roaming for USA and increased spend cap but I can’t make or receive any calls

@Ljw7 : Are you on contract or PAYG? Did you use that SIM for making calls or texts in UK before you left to go abroad?

If you are on contract, did you activate roaming on your EE a/c before you left UK by texting ROAMING to 150? Having a roaming billing add-on doesn't of itself activate roaming on your a/c. Having roaming activated on your EE a/c, not just on your device, is crucial to using your contract SIM abroad.

Often just rebooting the phone is the simple remedy. Also try selecting a network manually rather than auto. Otherwise you need to call CS to get your roaming activated. Try calling CS on the Freephone no. in my sig. on Skype over WiFi. It should be free.

Does your phone show a connection to any US networks? If not, then your underlying reason is lack of coverage, which is very likely caused by lack of roaming facility.

Without a network connection - then anything reliant on network coverage will fail - this includes calls, texts & mobile data.

If you do have a local network connection, but are unable to make or receive calls, then your issue could be something different. Let's clarify, as many people confuse a billing add-on with the roaming facility. The former is useless without the latter,
